Christ Jesus his not a man like any other but he show us how to become acceptable to his father and God ,
Jn 3:21 But whoever lives by the truth comes into the light, so that it may be seen plainly that what he has done has been done through God.”
Jn 4:23 Yet a time is coming and has now come when the true worshipers will worship the Father in spirit and truth, for they are the kind of worshipers the Father seeks. Jn 4:24 God is spirit, and his worshipers must worship in spirit and in truth.”
yes by building up the truth of God in us in our hearts ,
Heb 5:7 During the days of Jesus’ life on earth, he offered up prayers and petitions with loud cries and tears to the one who could save him from death, and he was heard because of his reverent submission. Heb 5:8 Although he was a son, he learned obedience from what he suffered Heb 5:9 and, once made perfect, he became the source of eternal salvation for all who obey him Heb 5:10 and was designated by God to be high priest in the order of Melchizedek.
2Co 5:1 Now we know that if the earthly tent we live in is destroyed, we have a building from God, an eternal house in heaven, not built by human hands. 2Co 5:2 Meanwhile we groan, longing to be clothed with our heavenly dwelling, 2Co 5:3 because when we are clothed, we will not be found naked. 2Co 5:4 For while we are in this tent, we groan and are burdened, because we do not wish to be unclothed but to be clothed with our heavenly dwelling, so that what is mortal may be swallowed up by life. 2Co 5:5 Now it is God who has made us for this very purpose and has given us the Spirit as a deposit, guaranteeing what is to come. 2Co 5:6 Therefore we are always confident and know that as long as we are at home in the body we are away from the Lord. 2Co 5:7 We live by faith, not by sight. 2Co 5:8 We are confident, I say, and would prefer to be away from the body and at home with the Lord. 2Co 5:9 So we make it our goal to please him, whether we are at home in the body or away from it. 2Co 5:10 For we must all appear before the judgment seat of Christ, that each one may receive what is due him for the things done while in the body, whether good or bad.
the spirit talked about in these scriptures is the faith that is given through his son ;the hope that God has given so that we can be saved
2Co 3:14 But their minds were made dull, for to this day the same veil remains when the old covenant is read. It has not been removed, because only in Christ is it taken away. 2Co 3:15 Even to this day when Moses is read, a veil covers their hearts.
2Co 3:16 But whenever anyone turns to the Lord, the veil is taken away.
2Co 3:17 Now the Lord is the Spirit, and where the Spirit of the Lord is, there is freedom. 2Co 3:18 And we, who with unveiled faces all reflect the Lord’s glory, are being transformed into his likeness with ever-increasing glory, which comes from the Lord, who is the Spirit.
yes this verse 16 is indeed the key to be saved ;for the truth has been spoken by Jesus the Christ and son of God
but if we do not accept his truth we will not be saved for the veil as remained on our hearts
