Preaching condemnation to others at the name of sins we know we do not commit is not the gospel of salvation. Preaching repentance and remission of sins at the name of JESUS CHRIST is the true gospel.

For in this, man is made to know he have to let go of his previous self, accept JESUS CHRIST as his LORD and Saviour, have his sins forgiven and a new life given unto eternal salvation, the gift of GOD, a new beginning:

Luke 24:46-47 And said unto them, Thus it is written, and thus it behoved Christ to suffer, and to rise from the dead the third day:
And that repentance and remission of sins should be preached in his name among all nations, beginning at Jerusalem.

This is why our LORD JESUS CHRIST made the world know the about the love of GOD towards mankind, which for the same love had to give up His only begotten Son as the pure sacrifice for our salvation:

John 3:15-16 That whosoever believeth in him should not perish, but have eternal life.
For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.

But despite this love, the LORD JESUS CHRIST made the world realize the benefit of believing and danger of unbelief. For in unbelief lies the eternal condemnation without excuses nor ignorance:

John 3:18 He that believeth on him is not condemned: but he that believeth not is condemned already, because he hath not believed in the name of the only begotten Son of God.

John 3:36 He that believeth on the Son hath everlasting life: and he that believeth not the Son shall not see life; but the wrath of God abideth on him.

In below quote, He made it known that He didn't come to condemn us but to save us, because He knows us already. Condemnation will only come when we reject Him and what He did for us and refusal to accept His light:

John 3:17, 19 For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
And this is the condemnation, that light is come into the world, and men loved darkness rather than light, because their deeds were evil.

GOD knows we are sinners, and to save us is why He sent His only begotten Son. When we believe and accept His Son, the HOLY SPIRIT comes into us to direct us and teach us to keep to the commandments of JESUS CHRIST.

That is when we become a new creature, walking with GOD and worshipping Him in the Spirit, and not after the flesh, because we are not to remain our former self as when we do not know GOD nor the Way.

Therefore, may the LORD JESUS CHRIST keep us in Him till the end in JESUS name.

Amen.
