Matthew 8:29
Two demon possessed men knew who Jesus was, but the others around Jesus did not. Jesus did things and explained things that plainly showed who he was. When he healed the paralytic, he did it for the purpose of showing them he had the authority to forgive sins. The Pharisees’ statement, “who but God can forgive sins” is true, so we can know Jesus is God. Jesus uses the term "Son of Man" which refers to the second person of the Trinity, the one who became flesh and dwelt among us – the one who can forgive sins.
They found it difficult to believe what was right in front of them, and we also find it difficult. Maybe knowing this – that it is difficult - will help us to get along during our own times. Others, after all, have had difficulties grasping the truth that was plain before them. Knowing this, we can work a little harder, try harder, be a little more patient, dig a little deeper, look more closely, balancing the concept of eternity with the present time. We can also know, and not be distressed, at the existence of others who do not, cannot, will not, believe what is set before them. That others will insist on their own version of who God is in the face of what God shows them should not keep us from being locked onto the truth.
