1st John 1:9
If we confess our sins, He is faithful and just to forgive us our sins, and to cleanse us from all unrighteousness.
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.
For God sent not his Son into the world to condemn the world; but that the world through him might be saved.
