Charles H. Spurgeon on Psalms 123:1

The lifting up the eyes, implies faith and confident persuasion that God is ready and willing to help us. The very lifting up of the bodily eyes towards heaven is an expression of this inward trust: so David in effect saith, From thee, Lord, I expect relief, and the fulfilling of thy promises. So that there is faith in it, that faith which is the evidence of things not seen. How great soever the darkness of our calamities be, though the clouds of present troubles thicken about us, and hide the Lord's care and loving kindness from us, yet faith must look through all to his power and constancy of truth and love. The eye of faith is a clear, piercing, eagle eye: Moses "endured, as seeing him who is invisible:" Heb 11:27. Faith seeth things afar off in the promises (Heb 11:13), at a greater distance than the eye of nature can reach to. Take it either for the eye of the body, or the mind, faith will draw comfort not only from that which is invisible, but also from that which is future as well as invisible; its supports lie in the other world, and in things which are yet to come. —Thomas Manton.
