How does God draw us out of the whirlpool of evil?
God does not just look on as man gradually destroys himself and the world around him through the chain reaction of sin. He sends us Jesus Christ, the Savior and Redeemer, who snatches us from the power of sin.
"No one can help me" - this maxim of human experience - is no longer accurate. Wherever man may have strayed by his sins, God the Father has sent his Son there. The consequence of sin is death (cf. Rom 6:23). Another consequence of sin, however, is the marvelous solidarity of God, who sends us Jesus as our friend and Savior. Therefore original sin is also called felix culpa (= happy fault): "O happy fault ... which gained for us so great a Redeemer!" (Liturgy of the Easter Vigil). (YOUCAT question 70)
The idea of felix culpa is to me an antidote to the idea I used to have that it is not fair that I should have to suffer for what Adam and Eve did. Rather, in response to what Adam and Eve did, God provided a Savior, by whom I am blessed.
Thomas Aquinas said that God only allowed evil because he would bring out of it a greater good. That greater good is the redemption Jesus obtained for us on the cross. As one of my favorite hymns says, "Amazing love, how can it be, that thou my God shouldst die for me."
