In Matthew 5:48 –
“Be ye therefore perfect, even as your Father which is in heaven is perfect.”

In Matthew 6:1 –
“… otherwise ye have no reward of your Father which is in heaven.”

Matthew 7:21 –
“Not every one that sayeth unto me (Jesus), Lord, Lord, shall enter into the kingdom of heaven: but he that doeth the will of my Father, which is in heaven.”

N.B. The word ‘Lord’ here was translated as Rabb in the Arabic version of the Bible so that people may be convinced that Jesus is God! But if one studies the rest of the verse, one will note that the verse bears testimony to the subservience (to God’s Will) of the Messiah (Jesus). Therefore the correct translation should be:

“Not every one that sayeth to me, O my Master, shall enter into the kingdom of heaven, but he that doeth the will of my Father which is in heaven.”

It is obvious from the above readings from the Bible that the term ‘Father’ is used for God in numerous places in the Bible. It is never used exclusively for the Messiah (Jesus).

Matthew 11:25 –
“At that time Jesus answered and said, ‘I thank Thee, O Father, Lord of heaven and earth, because Thou hast hid these things from the wise and prudent and has revealed them unto babes.'”
