No one is arguing Jesus is our justification. “No man” can determine your salvation but yourself. That is why Jesus says repent and be baptized. Baptism erases all sin on your soul. Because we are human we sin and need forgiveness for sins after baptism, that is when we use the sacrament of confession. Through the sacraments we gain sactfiying grace that help us live as He wants us to and prepares our soul for heaven.
Um, didn’t you post that a person can lose then regaing their Justification?
It's not grace if we have to perform to receive it.
It's wages due.
God freely pours out grace in our hearts through faith in Jesus.
Ephesians 1:3-10 Blessed be the God and Father of our Lord Jesus Christ, who has blessed us in Christ with every spiritual blessing in the heavenly places, even as he chose us in him before the foundation of the world, that we should be holy and blameless before him. In love he predestined us for adoption as sons through Jesus Christ, according to the purpose of his will, to the praise of his glorious grace, with which he has blessed us in the Beloved. In him we have redemption through his blood, the forgiveness of our trespasses, according to the riches of his grace, which he lavished upon us, in all wisdom and insight making known to us the mystery of his will, according to his purpose, which he set forth in Christ as a plan for the fullness of time, to unite all things in him, things in heaven and things on earth.
Romans 5:1-2 Therefore, since we have been justified by faith, we have peace with God through our Lord Jesus Christ. Through him we have also obtained access by faith into this grace in which we stand, and we rejoice in hope of the glory of God.
John 1:14-17 And the Word became flesh and dwelt among us, and we have seen his glory, glory as of the only Son from the Father, full of grace and truth. (John bore witness about him, and cried out, “This was he of whom I said, ‘He who comes after me ranks before me, because he was before me.’”) For from his fullness we have all received, grace upon grace. For the law was given through Moses; grace and truth came through Jesus Christ.
