1 John tells us, “Little Children” [of the Father] that if and when we sin, we have “an advocate with the Father, Jesus Christ the righteous: and he is the propitiation for our sins: and not for ours only, but also for the sins of the whole world” (1 John 2:1-2).
Again you are warned that your false doctrine and false gospel of maintaining salvation by works is doubly cursed (Gal 1:8-9).
As for 1 John, it would be best if one would study the WHOLE book of scripture. John is very clear:
1Jn 3:7 Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous.
1Jn 3:8 Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil.
