He was chosen before the creation of the world, but was revealed in these last times for your sake. 21Through him you believe in God, who raised him from the dead and glorified him, and so your faith and hope are in God. (I Peter 1:20-21 NIV)
A person cannot believe in the one true God who created the universe without accepting Jesus as his Lord and Savior now that God has chosen to reveal Himself through His Son. Jesus reveals God to us. Jesus, who is One with God from eternity past shows us the character of God in His character. He shows us the love and mercy of God by dying on the cross for our sins, and He showed the power of God when He was raised from the dead.
It is just as the Apostle John said:
“No one has ever seen God, but the one and only Son, who is himself God and is in closest relationship with the Father, has made him known.” (John 1:18 NIV).
