Your statement: How can any mortal ever begin to know or think what or how Jesus feels.
Answer: Start by reading the Bible. There is much to be learned about the love of God. Jesus is the manifestation of that love and His worldly ministry provided numerous examples of "feelings" from which we can gain understanding of how much God loves us. Jesus had compassion, Jesus wept, Jesus said that His soul was exceeding sorrowful and heavy at Gethsemane, and there are other examples.
