John 14:6 King James Version (KJV)
6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
The scripture above can be explained like this, the spirit of Jesus is the way to God in heaven, the spirit of Jesus is the word of God in heaven, and the spirit of Jesus is the eternal life of God in heaven: no man can go to God in heaven but by having the spirit of God which is the spirit of Jesus.
This is what Jesus meant when he said no man has ascended up into heaven but he that came down from heaven, which is the spirit of Jesus. Without the spirit of Jesus you will not enter the Spirit of God: which is the kingdom of God.
I am reminded of these verses:
Deuteronomy 30:10-16 “However, all this will happen only if you pay attention to what
Adonai your God says, so that you obey his
mitzvot and regulations which are written in this book of the
Torah, if you turn to
Adonai your God with all your heart and all your being.
(LY: vi) 11 For this
mitzvah which I am giving you today is not too hard for you, it is not beyond your reach. 12 It isn’t in the sky, so that you need to ask, ‘Who will go up into the sky for us, bring it to us and make us hear it, so that we can obey it?’ 13 Likewise, it isn’t beyond the sea, so that you need to ask, ‘Who will cross the sea for us, bring it to us and make us hear it, so that we can obey it?’ 14 On the contrary, the word is very close to you — in your mouth, even in your heart; therefore, you can do it!
(RY: iv, LY: vii) 15 “Look! I am presenting you today with, on the one hand, life and good; and on the other, death and evil — 16 in that I am ordering you today to love
Adonai your God, to follow his ways, and to obey his
mitzvot, regulations and rulings ; for if you do, you will live and increase your numbers; and
Adonai your God will bless you in the land you are entering in order to take possession of it.
Romans 10:4-10 For Moshe writes about the righteousness grounded in the Torah that the person who does these things will attain life through them. 6 Moreover, the righteousness grounded in trusting says: “Do not say in your heart, ‘Who will ascend to heaven?’” — that is, to bring the Messiah down — 7 or, “‘Who will descend into Sh’ol?’” — that is, to bring the Messiah up from the dead. 8 What, then, does it say? “The word is near you, in your mouth and in your heart.” — that is, the word about trust which we proclaim, namely, 9 that if you acknowledge publicly with your mouth that Yeshua is Lord and trust in your heart that God raised him from the dead, you will be delivered. 10 For with the heart one goes on trusting and thus continues toward righteousness, while with the mouth one keeps on making public acknowledgement and thus continues toward deliverance.

The Torah is the way (Deuteronomy 10:11-12, Psalm 119:1, Jeremiah 6:16-19), the truth (Psalm 119:142, Psalm 19:7, Nehemiah 9:13), and the life (Deuteronomy 30:15-16, Proverbs 3:18, Matthew 19:17), Jesus is the way, the truth, and the life (John 14:6), the Torah is God's Word and and Jesus is God's Word made flesh, so they are the same way, truth, and life.
