The prophet Isaiah wrote, "The virgin will be with child and will give birth to a son" (Isaiah 7:14). Jesus fulfilled that promise when He was born to Mary. He also fulfilled mankind's search for a Hero. Only a perfect man could die to save the world, and only God Himself could be that perfect man. When Jesus died on the cross, His sacrifice was for our sins. And when Jesus rose from the grave, He proved His true identity. Jesus said, "I am the way and the truth and the life. No one comes to the Father except through Me" (John 14:6). John 3:16 says, "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." In John 10:30, Jesus said, "I and the Father are one." 1 John 5:11-12 says, "God has given us eternal life, and this life is in His Son. He who has the Son has life; he who does not have the Son of God does not have life."
