Anonymous asked: 2) Why did Jesus have to die on the cross for our sins? God is omnipotent so He could have forgiven us as easily as saying "let there be light".
As we read and study the Bible, it becomes clear that God is the same in the Old and New Testaments. Even though the Bible is 66 individual books written on two (or possibly three) continents, in three different languages, over a period of approximately 1500 years by more than 40 authors, it remains one unified book from beginning to end without contradiction. In it we see how a loving, merciful, and just God deals with sinful men in all kinds of situations. Truly, the Bible is God’s love letter to mankind. God’s love for His creation, especially for mankind, is evident all through Scripture. Throughout the Bible we see God lovingly and mercifully calling people into a special relationship with Himself, not because they deserve it, but because He is a gracious and merciful God, slow to anger and abundant in loving-kindness and truth. Yet we also see a holy and righteous God who is the Judge of all those who disobey His Word and refuse to worship Him, turning instead to worship gods of their own creation (Romans chapter 1).
Because of God’s righteous and holy character, all sin—past, present, and future—must be judged. Yet God in His infinite love has provided a payment for sin and a way of reconciliation so that sinful man can escape His wrath. We see this wonderful truth in verses like 1 John 4:10: “This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins.” In the Old Testament, God provided a sacrificial system whereby atonement could be made for sin. However, this sacrificial system was only temporary and merely looked forward to the coming of Jesus Christ who would die on the cross to make a complete substitutionary atonement for sin. The Savior who was promised in the Old Testament is fully revealed in the New Testament. Only envisioned in the Old Testament, the ultimate expression of God’s love, the sending of His Son Jesus Christ, is revealed in all its glory in the New Testament. Both the Old and the New Testaments were given “to make us wise unto salvation” (2 Timothy 3:15). When we study the Testaments closely, it is evident that God “does not change like shifting shadows” (James 1:17).
