That is the entire point - his death and resurrection are a meaningless episode otherwise. The God of Abraham did not need a new miracle to demosntrate His power.
Paul acknowledging Jesus' humanity does not mean a denial of His divinity.
God's statements in Numbers were accurate at the time of Numbers. He chose to reveal more to us in the person of His Son, the Lord Jesus Christ - the New Testament was given for a purpose - to reveal elements of God's plan for the world which had not yet been revealed in Numbers.
God is not a half and half. Jesus never explicitly states "I am God", when it would have been so easy to do so. Instead you read into the text something that is not there. He DOES tells us EXPLICITLY, in no uncertain terms though, that he is a MAN! :)

His death is unfortunate but was not necessary for the salvation of mankind. Even Jesus himself tells us how to have ternal life.
Matthew 19
16 And, behold, one came and said unto him, Good Master, what good thing shall I do, that I may have eternal life?
17 And he said unto him, Why callest thou me good? there is none good but one, that is, God: but if thou wilt enter into life, keep the commandments.
A twofer!! :)
