R. Albert Mohler said:
The third great movement in the Christian metanarrative begins with the affirmation that God’s purpose from the beginning was to redeem a people through the blood of his Son –- and that he does this in order to show the excellence of his name throughout eternity. The God of the Bible is not a divine strategist, ready with a new plan in the event his original plan fails. The God of the Bible is sovereign and completely able to accomplish his purposes. Thus, when we come to the great act of God for our redemption, we come to the very heart of God’s self-revelation.
Beyond this, an adequate understanding of human sin brings us to the inescapable conclusion that there is absolutely nothing that the human creature can do to rescue himself from his plight. We find ourselves in an insoluble situation and are brought face to face with our own finitude. What is worse, all our efforts to solve the problem on our own lead only into an even deeper complex of sin. We are rebels to the core, and our attempts to justify ourselves lead only into deeper levels of sinfulness.
