All of the Bible is held together by God’s love for His people, the Jews. He also loves all of mankind, no matter what ethnic background or skin color they may have. Our problem with God’s love for us is that we can’t understand the depth of it. Why would God love people who hate Him? Why would He send Jesus to die on a cross for people that hate Him and His message?
Because of God’s promise to Eve and Adam that “the Seed of the woman will crush the head of the snake”, meaning Jesus would come and vanquish Satan and his temptation paying the price for ALL of mankind so they could regain their place in God’s house. This message runs all through the Bible and is fulfilled entirely when Jesus is born and grows in a village in Israel. Without God’s promise of a Redeemer and the fulfillment of that promise in the New Testament, there would be no gospel to preach and no salvation for mankind.
John 3:16-17 tells the whole gospel message in just a few words: For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. 17 For God sent not his Son into the world to condemn the world; but that the world through him might be saved. 18 He that believeth on him is not condemned: but he that believeth not is condemned already because he hath not believed in the name of the only begotten Son of God.
God created us as living souls so that we can commune with Him. He had this relationship in the beginning and God will bring us to Himself through the blood of Jesus. If we will believe in Jesus as our Savior and turn away from our old life and walk-in “newness of life in Christ Jesus“.
