You said salvation is from sin, is that mean after accepting the Lord, we never sin?
He accepts you if you truly repent.
Genuine salvation is wrought via a wholehearted yielding to the divine influence of God upon the heart.
Grace = Divine influence of God upon the heart.
Faith = Faithfulness and fidelity to God, ie. wholehearted yielding.
Saved by grace through faith (Eph 2:8) is the WORKING DYNAMIC by which we are QUICKENED (Eph 2:5) and thus made alive to God in the Spirit.
This is why James wrote...
Jas 1:21 Wherefore lay apart all filthiness and superfluity of naughtiness, and receive with meekness the engrafted word, which is able to save your souls.
Jas 1:22 But be ye doers of the word, and not hearers only, deceiving your own selves.
ALL filthiness and wickedness MUST be laid aside before one can receive the implanted word which saves the soul.
Serving sin is the OPPOSITE of receiving the implanted word which is why wr cannot do both. We cannot receive God in rebellion.
The church system preaches a false gospel premised upon substitution by which they view salvation as a POSITION as opposed to salvation being a MANIFEST REALITY of abiding in love.
Love does not produce sin. Anyone sinning is not saved because they do not love.
1Jn 4:16 And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him.
1Jn 4:17 Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.
As He is, so are we in this world.
Professing Christianity at large utterly denies that statement and instead defends ongoing sinning as part of the fake salvation they believe in.
They don't believe what the Bible plainly teaches, they just ignore it.
