"If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness." - 1 John 1:9

but

"If we deliberately keep on sinning after we have received the knowledge of the truth, no sacrifice for sins is left, but only a fearful expectation of judgment and of raging fire that will consume the enemies of God." - Hebrews 10:26
