If Jesus was God, why did he not know who had touched him? (Mark 5:30)

If Jesus was God, why did he not know what was going to happen on the Day of Judgment? But of that day or that Hour no one knows, not even the Angels in Heaven, not the Son but only the Father. (Mark 13:32)

If Jesus was God, why would he say that he was sent by God? (John 6:29)

If Jesus was God, what need did he have to pray? (Mark 1:35, Luke 5:16)

Jesus is reported to have said: He who receives you receives me, and he who receives me receives him who sent me (Matthew 10:40, Luke 10:16, John 12:44). Who sent Jesus if he himself was God?
