I always use
Romans 3:28 to assert my belief that no Christian can or ever will be justified before God by the works of the law (good works, etc.).
This is true!
I struggle comprehending verses such as
1 John 5:3-4, which state that the true children of God obey his commandments.
What are His commandments according to John?
1 John 5:5-6
5 But whoever keeps His word, truly the love of God is perfected in him. By this we know that we are in Him.
6 He who says he abides in Him ought himself also to walk just as He walked.
We abide in Christ by the Holy Spirit and lean not on our own understanding, but on Him. He gives us our daily bread, our manna, His Word, His commandments. Our conscience bears witness that we are in Him.
24 Now he who keeps His commandments abides in Him, and He in him. And by this we know that He abides in us, by the Spirit whom He has given us.
The commandments are not an external rule set, but an internal whispering to the heart. A heightened conscience. The law written on our hearts.
The only problem with this is that I struggle with sin everyday
If this were not a public forum I would ask you, "What sin are you struggling with?", but it may not be appropriate to share here. Nevertheless, I would highly encourage you to do whatever it takes to remove any sin from your life. Sin is often described as some kind of inescapable disease. And it would have been if Jesus had not cured it. And not only did He cure it, but you are cured as well. So why do you sin? Because you haven't realized that you don't have to. You are child of God, born again, a new creation. You are not a sinner. You are a saint, who at the moment, sins. But really, the true you, is a saint. When you received Jesus you died, that is, your sinful inclination died. Jesus rose up in you and you are now a new creation. Your normal inclination is now to do good. Not evil. But you may be caught in a habitual cycle. Confront it. Remove it. Do whatever it takes. Sin robs a person of joy and confidence in God. You can be set free and you don't have to live in sin forevermore on this earth. I will say again, confront it: in what environment do you sin? Do not enter that environment. Change it. Do something active to actually stop it from happening until the habit is gone. Don't give up. Especially make sure you don't get into guilt. Guilt doesn't help. There is no condemnation for those in Jesus Christ (Romans 8:1). Sin hurts you and the people around you. Stay away from it. Yes, God loves you even in your sin, but He loves you too much to leave you in that cycle. He will give you the strength to get out.
I also don't understand the meaning of faith without works is dead (
James 2:14-17).
Faith in God works. There are spiritual gifts or spiritual works such as prophesying. And there are good works such as the fruits of the Spirit. Focus on God and His love, He will bring about these things in your life. We don't need to struggle to make good works flow in our life. We worship God and love people. Good works happen naturally when we learn to just be ourselves in God. But what is the meaning of "faith", without any of these works? Faith in what? It would be just lip service. Faith believes in God, invites Him in to our lives, and submits everything to Him - then we are truly free and able to be ourselves.
Is it possible to keep God's commandments?
Yes. His commandments are not a burden because they are not an external rule set. They are synonymous with walking in the Spirit. And walking in the Spirit is not an airy fairy ideal. It is just being yourself and listening to Him. God gives us a big green light, but every now and then a red light appears, so we don't walk in that direction. He doesn't usually tell us individual things to do like "have a shower now", but He might one day say "I love you, you are awesome, let's spend some time together".
Is it good enough to just believe in Christ and just believing will save me? Or am I saved by faith and obedience?
Believing will save you. Not believing that He existed, but believing and receiving His salvation. Receiving a Spirit to spirit connection that comes when you confess Jesus as Lord of your life. You are not saved by faith and obedience. You are saved by faith. Obedience is something we all grow in, but like I said earlier, this is not obedience to laws, but obedience to His Love. Learning to walk in Him intimately like Enoch. Just enjoy His company and obedience follows. Although, I really don't like the word "obedience", it conjures up images of a controlling God forcing us to do something. Better is relationship. Faith and relationship are a good mix.
