Charles H. Spurgeon on Psalms 61:2

I will cry unto thee. There is in this expression an endeavour to approach unto God; as you do when you cry after one whom you see at a distance, and are afraid he will go farther from you. It is the great work of faith to cry out after God, at a distance, when you are afraid lest at the next turn he should be quite out of sight. Crying to the Lord supposes him to be withdrawing or departing. John Owen.
