God is faithful and fair. If we admit that we have sinned, he
will forgive us our sins. He will forgive every wrong thing we
have done. He will make us pure."
Since we cannot take
our sins to heaven (no sin is allowed into heaven), what can
we do with them. Jesus says we must confess (tell them) to Him
and ask His forgiveness. He will be faithful to forgive us. That
is the only way we can be pure (cleaned up) enough to enter into
heaven when it is time for us to go there. We are not really
cleaned up without Jesus giving us His cleanness and goodness.
That is when we become right in God's eyes. When He sees His
Son, Jesus in our hearts, we become His children.
