The promise is generous in its invitation. Ail that come - there is no special mark. It doesn't matter what sort of a person comes, how good they are or how bad. Perhaps you are not as generous as that with yourself. Perhaps you are saying that God would never have anything to do with so grave a sinner as yourself.
Many people are deeply aware of their sin.
Many feel that God would have nothing to do with them. This God would. He gave his Son for sinners and his Son says that he will turn away no-one who comes. There is no limit of any kind put upon our coming or the way in which we come, as long as we come to Jesus. There is no limitation as to age, or place or means.
