Alas! how strange and how sad is the reception which this merciful invitation receives from so many of us! Some of you never hear it at all. Standing in the very focus where the sounds converge, you are deaf, as if a man behind the veil of the falling water of Niagara, on that rocky shelf there, should hear nothing. From every corner of the universe that voice comes; from all the providences and events of our lives that voice comes; from the life and death of Jesus Christ that voice comes; and not a sound reaches your ears. 'Having ears, they hear not,' and some of us might take the Psalmist's answer, with one sad word added, as ours--'When Thou saidst, Seek ye My face, my heart said unto Thee, Thy face, Lord, will I _not_ seek.' Brethren! it is heaven on earth to say, 'Thou dost call, and I answer. Speak, Lord, for Thy servant heareth.' Yet you shut yourselves up to, and with, misery and vanity, if you so deal with God's merciful summons as some of us are dealing with it, so that He has to say, 'I called, and ye refused; I stretched out My hand, and no man regarded.' III. Lastly, we have here a prayer built upon both the invitation and the acceptance. 'Hide not Thy face far from me.' That prayer implies that God will not contradict Himself. His promises are commandments. If He bids us seek He binds Himself to show. His veracity, His unchangeableness, are pledged to this, that no man who yields to His invitation will be balked of his desire. He does not hold out the gift in His hand, and then twitch it away when we put out encouraged and stimulated hands to grasp it. You have seen children flashing bright reflections from a mirror on to a wall, and delighting to direct them away to another spot, when a hand has been put out to touch them. That is not how God does. The light that He reveals is steady, and whosoever turns his face to it will be irradiated by its brightness.
