I think Jesus did not want to enclosed His divinity to soon or too much, not wanting to jeopardize His primary calling towards the cross. The Jews then were so embedded with ideas of a politically driven Messiah who would save them from their misery of the Roman dominant empire and ultimately reign forever just as the prophets have spoken. If He were to exclaim His divinity overtly He might not be able to penetrate and win the minds of the Jews at that time which he could have been stone prematurely for blaspheming so much as to rightly exalt himself as equal to God. I believe His main mission on earth was to complete salvation for the hope of humanity. His resurrection and ascension in it self, in fact clearly shows that He is divinely intervened and are one of sufficient evidences although not stressed upon.
