For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have everlasting life. For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
God’s plan of redemption of mankind through Jesus Christ is eternal. Moreover, the Bible tells us we were chosen in Christ Jesus before the foundations of the world were laid in place. Jesus is God, He is the Second Person of the Trinity. Jesus in His person is of the same essence and nature as God the Father. The word used when speaking of Jesus nature as God in the Bible is homoousios (ho’mo-u’sios) which means Jesus is one and the same as God the Father. What John is telling us is that God loved us so much that God Himself stepped out of eternity and took on humanity in the incarnation. Jesus the eternal God of Heaven, added humanity to His divinity, to forever become the God-man Jesus Christ.
Jesus is fully God and fully man and shares the same nature and divinity as God the Father. Jesus came for no other purpose than to die on the cross for our sins. Jesus, who is sinless God, took upon Himself the punishment for all of our sins past, present and future. That we through our faith in Him have eternal life and a restored relationship with God. John goes on to say that all of us who place our faith in Jesus are not condemned, but have eternal life and we are saved through His sacrifice for us. And those who do not believe in Jesus and do not accept Him as their Savior are already condemned because they did not believe in the name of the only begotten Son of God. Moreover, it’s important to remember all humanity is condemned because of the fall of mankind and therefore salvation is through grace alone, which God freely offers by faith alone in Jesus Christ our Lord.
