Jesus said He was God. He proved it by His life, His words, His deeds, and His love.
“But God, who is rich in mercy, for his great love wherewith he loved us, Even when we were dead in sins, hath quickened us together with Christ, (by grace ye are saved;)”
-Ephesians 2:4–5
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life”
-John 3:16
