Matthew 17:19-21 (KJV)
19 Then came the disciples to Jesus apart, and said, Why could not we cast him out?
20 And Jesus said unto them, Because of your unbelief: for verily I say unto you, If ye have faith as a grain of mustard seed, ye shall say unto this mountain, Remove hence to yonder place; and it shall remove; and nothing shall be impossible unto you.
21 Howbeit this kind goeth not out but by prayer and fasting.
Angels, Jesus, Father, And Holy Spirit
Angels and Jesus are a lot alike, except for Jesus being God. They can both transform their bodies and simply appear in a room if they want to.
