The crucifixion doesn't bring to people automatically
forgiveness of the sins. First must preach the gospel and
they, who repent and accept word of God and believe to Jesus
Christ, only for them is valid forgiveness of the sins, but
not else. For them who don't want repent neither believe to
Jesus Christ, to them the gospel preaches the death and the
damnation. So, repent in your life and receive free gift of
God, which is salvation in Jesus Christ.
And saying (Jesus), The time is fulfilled, and the
kingdom of God is at hand: repent ye, and believe the
gospel. Mark 1:15
