Trump thinks he doesn't need to ask God's forgiveness

He has stated this numerous times. Donald Trump's spiritual mentor, Norman Vincent Peele, was a member of Milwood Lodge No. 1062 in Brooklyn, New York for 67 years. Peele was also a 33rd degree Scottish Rite Freemason.
The Bible commands that we must repent in order to go to heaven. Here are some of the verses (there are many more):

Matthew 3:2 "And saying, Repent ye: for the kingdom of heaven is at hand".

Luke 13:3 "I tell you, Nay: but, except ye repent, ye shall all likewise perish".

Matthew 4:17 "From that time Jesus began to preach, and to say, Repent: for the kingdom of heaven is at hand".

Acts 8:22 "Repent therefore of this thy wickedness, and pray God, if perhaps the thought of thine heart may be forgiven thee".
