It's such a comfort to know we can be forgiven for our sins. I guess the part that's hard for me to wrap my mind around is how those mass murderers - who are/were such evil people - can truly be saved but that is what God promises us. So I guess it's the transformation from evil to being saved (not God's forgiveness) that seems difficult to accept. For me, anyway.
Rejoice ever more. 1 Thessalonians 5:16
