Romans 5:16 "The gift is not like that which came through the one who sinned; for on the one hand the judgment arose from one transgression resulting in condemnation, but on the other hand the free gift arose from many transgressions resulting in justification."

Does God merely take a bad situation and turn it for good?  Find some positive note in the bad?  Actually, sin is part of his plan to accomplish his purposes of mercy, love and redemption. 

Acts 2:23 "delivered over by the predetermined plan and foreknowledge of God, you nailed to a cross by the hands of godless men and put Him to death." 

Acts 4:27-28 "For truly in this city there were gathered together against Your holy servant Jesus, whom You anointed, both Herod and Pontius Pilate, along with the Gentiles and the peoples of Israel, to do whatever Your hand and Your purpose predestined to occur."

The free gift that arose from many transgressions was part of God's plan from the beginning.  If you are trusting in Christ, then justification has been granted to you freely because of God.  What a gift, what undeserved favor bought for us at such a high price.
