John 14:1 Do not let your hearts be troubled. You believe in God; believe also in me.
The disciples knew the scriptures taught that God would love and care for them; Jesus now re-iterated those same sentiments in words.
Jesus came as a human being to be amongst us and to teach us how much He loves us – He wanted us to see God in person, or at least allow the disciples to see Him in person.
But this wording shows Jesus as being subservient to God in heaven at all times – even when being made equal to God! Look and learn.
