The religion of Islam will readily confess that Jesus was the Son the Man and its followers will quickly point out the number of times that Jesus referred to Himself with that title, but it readily denies that Jesus was the Son of God and its followers will quickly point out that Jesus never referred to Himself as such.
Regardless of the fact that Jesus did indeed refer to Himself as the Son of God and He confessed to be such before multiple people (Matthew 16:13-17, John 9:35-38) one of the key misunderstandings of Jesus’ nature when it comes to Islam is that the religion misses what the Son of Man taught about Himself when it comes to His authority.
In Mark 2:1-12 (a gospel that begins in a plain enough way concerning the nature of Jesus) Jesus proclaims and confesses to having the ability to do something that no mere righteous man would ever say unless it was absolutely true. After being accused of blasphemy Jesus tells a group of hard-hearted unbelievers He not only did what He did to prove a point, He said what He said so they wouldn’t miss the point – “Which is easier, to say to the paralytic, ‘Your sins are forgiven you,’ or to say, ‘Arise, take up your bed and walk’? But that you may know that the Son of Man has power on earth to forgive sins….”
The power, authority and ability on earth to forgive sins?! Jesus was a son and He was a man, but when Jesus referred to Himself as the Son of Man He was talking about much more than what you could see on the outside. It was a sign that pointed to who He was. It pointed to the Messianic nature that was on the inside, for only God Himself has the power, authority and ability to forgive sins.
Angels proclaimed it (Luke 1:35), the demons couldn’t deny it (Mark 5:7-8) and the apostles preached it (John 20:30-31) – Jesus, the Son of Man, is Immanuel, the Son of God.
If Jesus didn’t deny it, why should we?
“In the beginning was the Word, and the Word was with God, and the Word was God...And the Word became flesh and dwelt among us, and we beheld His glory, the glory as of the only begotten of the Father, full of grace and truth.” (John 1:1, 14)
