“For God so loved the world that he gave his one and only Son, that whoever believes in him shall not perish but have eternal life.” - John 3:16
God hates sin but He loves sinners. God sent His Son, Jesus Christ, to pay the penalty for our sins by dying on the cross in our place. Jesus, who is God, became a man and lived the life (without sin) that we cannot live (2 Corinthians 5:21; Hebrews 4:15), and died the death that we could not die (Romans 5:8). Our best efforts, all of our righteous acts, cannot restore our relationship with God. When Jesus died on the cross, He provided a way for us to have a right relationship with God here on earth and in heaven.
“For there is one God and one mediator between God and men, the man Christ Jesus.” -1 Timothy 2:5
"Some sights in the world astonish us once or twice and then grow commonplace. However, the Cross of Christ grows on us; the more we know of it, the more it surpasses knowledge. To a believer who has been saved for two thousand years, the sacrifice of Calvary is even more of a marvel than when he first saw it. That God Himself should take our nature and that, in that nature, He should die a death like a felon who is put on display on an execution post, in order to save us who were His enemies, is a thing that could not be believed if it had been told to us on any less authority than God's. It is altogether miraculous, and if you will let it take possession of you until it is poured out in your heart by the Holy Spirit, you will feel that there is nothing worth knowing, believing, or admiring compared to this. Nothing can ever rival our interest in the Cross of Christ. We may study many fields of knowledge, but the knowledge of a crucified Savior will still remain the most sublime of all the sciences." - Charles Spurgeon, Finding Peace in Life's Storms
