I think you will find that in the sentiment, "Only God can forgive sin", Jesus is plainly letting the cat out of the bag..... He would be explaining who He was.
(John 10:34 [UKJV])
Jesus answered them, Is it not written in your law, I said, All of you are gods?
(John 1:12 [UKJV])
But as many as received him, to them gave he power to become the sons of God, even to them that believe on his name:
(1John 4:17 [RNT])
Thus love has been made perfect with us so that we may have confidence on the day of judgment, because as God is we also are in this world.
(1John 3:2 [RNT])
Beloved, we are now children of God and it is not yet plain what we shall be. But we know that if he appears we shall be like him, for we shall see him as he is.
(John 10:35 [UKJV])
If he called them gods, unto whom the word of God came, and the scripture cannot be broken;
And if anyone wants to break scripture and froth about this, take it up with God.
