Jesus is God's perfect Son, He is God the Son. That means that He is God and He became a man and lived a perfect life. The Lord Jesus was the only person in all of history to ever live His entire life without sin.
But that's not the only thing that makes Him special. Jesus, the Son of God, chose to take punishment that He didn't deserve. He let Himself be nailed to a cross by people who didn't understand who He really was. He shed His blood on the cross and died, even though He had never done anything wrong.
Why? When He died He was taking the punishment for something He didn't even do. He was taking the punishment for all the sin that you and I and everyone in the world has ever done. The punishment was to die. And the Lord Jesus knew that the only way that your sin could be forgiven would be if He would die for you. Jesus died for your sins. The Bible says that "without the shedding of blood there is no [forgiveness] of sins". (Hebrews 9:22b)
As He died, the Lord Jesus said, "It is finished." Everything that needed to be done for your sins to be taken away had been done by Him on the cross.
They buried His body. But three days later He proved that He could take away your sins and give you everlasting life, by coming back to life Himself! And without dying again, He returned to Heaven, where He is alive today.
Because Jesus is God's Son who died for you, you can ask Jesus to make you a child of God right now! The white page talks about how.
