People say Jesus never claimed to be God. Jesus never used the sentence, "I am God," but He did make this claim in a number of ways. He claims to be one with the Father. He claimed to be "I AM" - a name uniquely associated with God. Sometimes a good way to see what Jesus was claiming is to note the reaction of the Jews around Him.
The Jews were monotheists. They took blasphemy very seriously, and claiming to be God was the highest blasphemy. They accused Jesus of blasphemy on several occasions. He was tried and convicted of blasphemy by the High Priest, which is why they asked Pilate to crucify Him. They rent their clothing at His claims.
In Matthew 9, Jesus tells a paralytic that his sins are forgiven, and the scribes said He was blaspheming because only God can forgive sins. Jesus then proves His authority to forgive by healing the man. He proved His claim to be God.
There are a number of ways Jesus claimed to be God and that is exactly what his audience of Jews understood Him to be doing. Watch their reactions.
