Who is the best prophet in Christianity? and is he the best human being in the eyes of God? The degree of how well God is worshipped varies from person to person, some do better deeds, have better morals, or do greater sacrifices than others, so it seems natural that there will be some human who is the best human in the eyes of God. I'm curious if Christians have some consensus on who is the best human or the most perfect human being, in terms of following God's orders. 

I am asking this question with the assumption that Jesus is not human and does not worship someone/something since He is God himself (my assumption may be wrong). I guess my question is more about who is the best worshipper of God? If it's Jesus then did Jesus actually "worship"? How so?
There is no consensus within Christianity about who is the 'best' prophet.

The Christian belief in the universal sinfulness of human beings (apart from God's grace) tends to mean that such comparisons are not encouraged.

As you intimated, Jesus is an exception to this. The vast majority of Christians believe that Jesus is both fully God and fully human. If your question had not excluded him he would unquestionably be 'the best prophet' in all senses, and he is also considered the 'best human being'.

Since there isn't a consensus (or doctrine) on this, we can only have the opinions of various Christians, which we cannot discuss on this site.
