Confess your sins and God will forgive you. It's a sure thing!!!
If we confess our sins, he is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 1 John 1:9.
That by two unchangeable things, in which it impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold upon the hope set before us: Which hope we have as an anchor of the soul, both sure and entereth into that within the veil; Whither the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchisedec. Hebrews 6:18-20.
