Crucifixion and faith to Jesus Christ is the prerequisite
for forgiveness of the sins. The repentance for
forgiveness of the sins has to be preached in the name of
Jesus Christ. Repentance (metanoeo = to change one’s
mind, to repent, to change one’s mind for better). Making
of the repentance means confessing and repenting of the
sins, such as also the Bible says:" If we confess our sins,
He is faithful and righteous that He may forgive us the
sins, and may cleanse us from all unrighteousness." Meaning
of repentance is also abandoning of the sins and that life
of the man change in accordance with word of the God.
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
