In the Gospel of Mark we read that people brought Jesus a man who was deaf and could hardly talk, and begged Jesus to heal him.
Before healing the man Jesus looked up to heaven sighed, said to him, “Ephphatha!” (which means “Be opened!”). The man’s ears were opened, his tongue was loosened and he began to speak plainly.
Jesus, the Creator of all things sighed. I believe Jesus sighed not because of size of the miracle but because of the mess the sin of Adam had made out of the world He created. It was not supposed to be this way.
I have the feeling Jesus is sighing with all the turmoil in the world today but sighing even more because many still have not accepted His invitation to be saved.
