“For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life.” John 3:16
The bad infection of sin cannot be treated by good works, self-effort, or religious tradition. That is like treating cancer with aspirin. You may feel better, but you have done nothing to solve the disease. Sin must be taken away, and that was done by Christ at the cross through His sacrificial death. Christ is the answer to sin. He is “the way, the truth, and the life” (John 14:6).
Paul penned the heart of the gospel in his second epistle to the Corinthians: “He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him” (2 Cor. 5:21). Martin Luther called this the “great exchange.” Jesus became what He was not (sin) in order that we might become what we are not (the righteousness of God).
The good news of the gospel is that our sin has been forgiven by Christ. He cleared away our guilt, died our death, and offers us reconciliation with God. The gift of God’s righteousness can be yours be simple faith in Him. Believe in Jesus Christ. Your sins will be taken away. You will become a child of God, rightly related to Him and assured of everlasting life with Him.
“...‘Behold, the Lamb of God who takes away the sin of the world!’” John 1:29
