The problem is that you need to understand when Jesus is speaking as God and when He is speaking as man. Jesus was both God and man, 100% of each. Jesus prayed, dealt with temptation, etc. as a man in order to be a righteous model for us to follow. He related to God as a man in order to show us how to do it.
Jesus also did things that only God can do. He exercized personal power over nature, death and demons. He also claimed to be eternal life, which is really over the top if Jesus is only a man. He also absolved sin from a person which even His enemies acknowledged as something belonging to God. He even recieves worship, before and after His resurrection/ascension.
In addition, Jesus is to be proclamed "Lord" which in the first century, when Bible was being written in the shadow of the Roman Empire, it was a very radical and dangerous thing to call anyone but Caeasar "Lord." You need to realize that "Lord" in terms of Caesar, was a defied title, and the Bible sets Jesus up as a deity in contest with Caesar. To declar Caesar as "Lord" was to acknowledge his deity. So when the writers of the NT declared that Jesus is "Lord" that deified rivalry between the god Caesar vs. the true "Lord" and "God" Jesus, would not have been lost on those believers in the first century. To declare Jesus as "Lord" was to proclaim Him as God.
I agree with Shiloh. Jesus can be 100% God and human, just as i am 100% human and 100% self-aware.
