Jesus, if at all, was a mere human, not a god ; and, at best, a credulous impostor. Think about the last words of Jesus -- "O' god, O god! Why hast thou forsaken me"! Does it sound as if they were the words of an "all powerful" god? If Jesus was god, then, was he crying and begging for mercy to himself with those words!! Strange!!
The Enigma of the Holy Trinity, ah yes, if faith wasn't complicated enough. A pretext to convince followers their inability to grasp these complexities is just proof of their human inadequacy, hence God appears that much more superior by comparison.
I realize its a difficult concept to grasp but Jesus was BOTH One with God AND completely separate and independant of Him. He was God AND Gods SON separately. He, the human Jesus, loved God as his Father. He, the spirit of God was One with God and as God.
That is a really complicated question. First you have to understand that the whole reason Jesus came to earth was to save people and show how to live without sin. The "Incarnation" (when God became man: Jesus) means that Jesus is fully human and fully God. He is not half each or God in a human body. Since he was living as a human, he was in the same situation where he was religious and could love God.
