4 For since the beginning of the world men have not heard, nor perceived by the ear, neither hath the eye seen, seen...: or, seen a God beside thee, which doeth so for him, etc O God, beside thee, what he hath prepared for him that waiteth for him.
English Standard Version
4 From of old no one has heard or perceived by the ear, no eye has seen a God besides you, who acts for those who wait for him.
4 Since before time began no one has ever imagined, No ear heard, no eye seen, a God like you who works for those who wait for him.
New King James Version
4 For since the beginning of the world Men have not heard nor perceived by the ear, Nor has the eye seen any God besides You, Who acts for the one who waits for Him.
New Living Translation
4 For since the world began, no ear has heard and no eye has seen a God like you, who works for those who wait for him!
They desire that God would manifest himself to them and for them, so that all may see it. This is applicable to the second coming of Christ, when the Lord himself shall descend from heaven. They plead what God had used to do, and had declared his gracious purpose to do, for his people. They need not fear being disappointed of it, for it is sure; or disappointed in it, for it is sufficient. The happiness of his people is bound up in what God has designed for them, and is preparing for them, and preparing them for; what he has done or will do. Can we believe this, and then think any thing too great to expect from his truth, power, and love? It is spiritual and cannot be comprehended by human understanding. It is ever ready. See what communion there is between a gracious God and a gracious soul. We must make conscience of doing our duty in every thing the Lord our God requires. Thou meetest him; this speaks his freeness and forwardness in doing them good. Though God has been angry with us for our sins, and justly, yet his anger has soon ended; but in his favour is life, which goes on and continues, and on that we depend for our salvation.
