Jesus is God. If Jesus was not God, His death would not have been sufficient to pay for the lives of all humans (1 John 2:2). A created being, which Jesus would be if He was not God, could not pay the infinite penalty required for sin. If Jesus was only a created being, he could atone for only one human life. A life for a life (Exodus 21:23). But only the Creator’s life could atone for the lives of all His creatures. Therefore, Jesus is indeed God the Son. Christ is Divine and His life is more equivalent than the lives of all humans because He is the Creator (Colossians 1:16).
And because Jesus is divine, He took upon Himself the redemption of mankind. Ever since Adam’s sin, every human has been guilty of breaking God’s righteous laws “For all have sinned and fall short of the glory of God” (Romans 3:23). Therefore, because of sin, everyone was sentenced to death and eternal separation from God.
A judge who simply pardons law-breakers isn’t a righteous judge. Likewise, Ignoring sin would make God an unjust judge because death is God’s judgement for sin “For the wages of sin is death” (Romans 6:23). Even good works cannot atone for sin because compared to God’s goodness, our works “are as filthy rags” (Isaiah 64:6).
And because “God is love” (1 John 4:8), He offered to sacrifice His own Son to redeem His fallen creation. “For God so loved the world that he gave his only begotten Son” (John 3:16). “Greater love has no one than this, than to lay down one’s life for his friends” (John 15:13). At the Cross God’s justice and love were fully satisfied and fulfilled.
