Life is in Christ and not the law because the law can't make us righteous. Wherefore Christ said,
39 Search the scriptures; for in them ye think ye have eternal life: and they are they which testify of me.
40 And ye will not come to me, that ye might have life.
In Matthew 19:17, Christ said that the way to enter eternal life is by obeying God's commandments and cited many others verses that say the same thing, so eternal life can be found in the Scriptures and the Pharisees were correct to search for it there, but they needed to recognize that the goal of everything in Scripture is to testify about how to know Jesus and come to him for eternal life. However, there can be any number of motivations for obeying God's law, some of which are correct while others are not, so our motivation for obeying God's law is important because only the correct motivations will lead to eternal life.
While there are many verses where Paul denied that we can earn our righteousness as a wage, such as Romans 3:28, Romans 4:4-5, Ephesians 2:8-9, Titus 3:5, Galatians 2:21, and Galatians 3:21, there are many other verses that show that our righteousness/salvation/eternal life requires us to be doers of the law, such as Romans 2:6-7, Romans 2:13, Ephesians 2:10, Titus 2:11-14, Galatians 3:26-29, James 2:17-24, Matthew 7:21-23, and Matthew 19:17, so the only way that I can see to reconcile both sets of verses is if there are motivations for why our righteousness/salvation/eternal life requires us to choose to be doers of the law other than in order to earn it as a wage, such as faith insofar as Romans 3:31 says that our faith upholds God's law.
I believe the tree of Life is through Christ The Bread of Life, and God's commandment is to eat him and therefore believe in the one He sent; and Christ's commandment is to love others as he has loved us. It's all about having the True Image of God shining in one's heart. This one righteous man, oh Jesus, that you would lay down your own life as an offering for sin, for such is His righteousness.
I agree that the tree of life is through Christ, who is the Bread of Life, though Christ is the living embodiment of the nature of God expressed through living in sinless obedience to God's law, so that is synonymous with Christ saying that the way to enter eternal life is through obeying God's commandments.
Galatians 2:21
I do not frustrate the grace of God: for if righteousness come by the law, then Christ is dead in vain.
3:21
Is the law then against the promises of God? God forbid: for if there had been a law given which could have given life, verily righteousness should have been by the law.
In Psalms 119:29-30, David wanted to put false ways far from him, for God to be gracious to him by teaching him to obey His law, and he chose the way of faithfulness, so this has always been the one and only way to become righteous by grace through faith. In Exodus 33:13, Moses wanted God to be gracious to him by teaching him His way that he might know Him and Israel too, and in Matthew 19:17, Jesus said that he would tell those who are workers of lawlessness to depart from him because he never knew them, so knowing God and Jesus is the goal of the law, which is eternal life John 17:3). So again the only way I can see to reconcile these verses is if there are correct motivations by which righteousness and eternal life come by the law, such as through faith, and an incorrect motivation by which righteousness and eternal life do not come by the law, such as earning it as a wage.
While it is true that Abraham believed God, so he was justified (Genesis 15:6), it is also true that he believed God, so he obeyed God's command to offer Isaac (Hebrews 11:17), so the same faith by which he was justified was also expressed as obedience to God, but he did not earn his justification as a wage (Romans 4:4-5). In James 2:21-24, it quotes Genesis 15:6 to make the case that Abraham was justified by his works when he offered Isaac, that his faith was active along with his works, and his faith completed his works, so he was justified by his works insofar as they were motivated by his faith, but not insofar as they were motivated by earning a wage.
1 Timothy 1:9
Knowing this, that the law is not made for a righteous man, but for the lawless and disobedient, for the ungodly and for sinners, for unholy and profane, for murderers of fathers and murderers of mothers, for manslayers,
In 1 Timothy 1:8, it says that God's law is good if we obey it properly, so the next verse should not be used to argue that it is not good to obey. In Isaiah 51:7, the righteous are those on whose heart is God's law. To say that someone has a character trait is to say that they are someone who chooses to take actions that express that character trait, so to say that someone is courageous is the say that they choose to take actions that express courage, and it would be contradictory for someone to be courageous while also being someone who chooses to not take actions that express courage. In the same way, to describe someone as righteous is to describe them as being same who chooses to take actions that express God's righteousness in accordance with His laws for how to do that, and it would be contradictory for someone to be righteous who chooses not to take actions that express God's righteousness. It would absurd to think that the doing what is righteous in obedience to God's law is only for the unrighteous, so once someone becomes righteous they are then free to do what is unrighteous in transgression of God's law. Someone who tries to uses 1 Timothy 1:9 to say that the law is only for the unrighteous to justify why the law is not for them and why they are free to do what is unrighteous thereby becomes someone that the law is for.
To use an analogy, instructions for how to build a computer and not made for experts who have built hundreds of computers, who are already acting in accordance with those instructions, but rather it is those who don't know how to build a computer who have the need to be taught instructions for how to do that. Instructions for how to do what is righteous are not needed to teach those who are already living righteously in accordance with those instructions, but rather those instructions are made to teach those who are unrighteous.
We have to go through the veil. We were under the law to bring us to Christ.
- Galatians 3:24
Wherefore the law was our schoolmaster to bring us unto Christ, that we might be justified by faith.

- Galatians 3:25
But after that faith is come, we are no longer under a schoolmaster.
Knowing God and Jesus is the goal of the law, so the law leads us to Jesus because it teaches us how to know him, or in other words, how to have a relationship with him, but does not lead us to him so that we can reject what he taught and go back to living in sin. Someone who disregarded everything that their schoolmaster taught them after they graduated would be missing the whole point of a schoolmaster. Now that Christ has come we are now under a superior teacher, but the subject matter is still how to walk in God's way in obedience to His law in accordance with what Jesus spent his ministry teaching by word and by example.
Galatians 3:26-29 for in Christ Jesus you are all sons of God, through faith. 27 For as many of you as were baptized into Christ have put on Christ. 28 There is neither Jew nor Greek, there is neither slave nor free, there is no male and female, for you are all one in Christ Jesus. 29 And if you are Christ's, then you are Abraham's offspring, heirs according to promise.
In 1 John 2:6, those who are in Christ are obligated to walk in the same way he walked, and he walked in obedience to God's law. A chip off of the old block is someone who has the same character or nature as their father, so this is the sense that Jesus is the Son of God insofar as the Son is the exact expression of God's nature (Hebrews 1:3), and the sense that we are sons of God when we are partaking in his nature through following his example. In John 8:39, Jesus said that if they were sons of Abraham, then they would be doing the same works that he did, so again the concept of sonship is in regard to expressing the same nature. Fruits of the Spirit are aspects of God's nature, so that is why in Romans 8:4-14 that those who are born of the Spirit are contrasted with those who have minds set on the flesh who refuse to submit to God's law, and why in 1 John 3:4-10, those who do not practice righteousness in obedience to God's law are not sons of God. In Matthew 23:23, Jesus said that faith is one of the weightier matters of God's law, so Galatians 3:26 says that in Christ we are all sons of God through faith is speaking about expressing God's nature through walking in obedience to His law.
Furthermore, in Genesis 18:19, God knew Abraham that he might teach his children and those of his household to walk in God's way by doing righteousness and justice that the Lord may bring to him all that He has promised, namely in Genesis 26:4-5, God will multiply Abraham offspring as the stars in the heave, to his offspring he will give all of these lands, and through his offspring all of the nations of the earth will be blessed. So the offspring that Abraham is multiplying is by teaching others to do the same works that he did by expressing God's nature through walking in His way in obedience to His law, and all of the promises were made Abraham and brought about because Abraham walked in God's way in obedience to His law, he taught his offspring how to do that, and because his offspring did that (Deuteronomy 30:15-16). Furthermore, the land would spit them out if they were not living in obedience to God's law, so all of the promises are connected with obedience through faith (Leviticus 18:28). God's law is how the offspring of Abraham knew how to walk in His way and be blessed (Psalms 119:1-3), so the the way for them to inherit the promise of being a blessing to the nations is by turning the nations from their wickedness and teaching them how to be blessed by walking in God's way. In Acts 3:25-26, Christ, who is the way, was sent as the ultimate fulfillment of that promise to bless us by turning us from our wickedness, so all of this is in regard to Galatians 3:26-29 connecting being a child of God in Christ, where we are doing the same works he did, with being a child of Abraham, heirs according to the promise, and this was the Gospel that was made known in advance to Abraham (Genesis 3:8) to repent for the Kingdom of God is at hand (Matthew 4:15-23). The Kingdom of God is where people are blessed and are a blessing to others through multiplying the nature of God by teaching people to repent from their wickedness and how to walk in God's way in obedience to His law.
