Blessed is he whose transgressions are forgiven,
whose sins are covered.
Blessed is the man whose sin the LORD does not count against him
and in whose spirit is no deceit.
When I kept silent, my bones wasted away
through my groaning all day long.
For day and night your hand was heavy upon me;
my strength was sapped as in the heat of summer.
Then I acknowledged my sin to you and did not cover up my iniquity.
I said, "I will confess my transgressions to the LORD" -
and you forgave the guilt of my sin.
(Psalm 32 verses 1-5 (NIV))

If we claim to be without sin,
we deceive ourselves and the truth is not in us.
If we confess our sins,
he is faithful and just and will forgive us our sins
and purify us from all unrighteousness.
(1 John chapter 1 verses 8 and 9 (NIV))

For God so loved the world
that he gave his one and only Son,
that whoever believes in him
shall not perish
but have eternal life.
(John chapter 3 verse 16)
