Psalms 31:7

I will be glad, and rejoice in thy mercy,....

He complains of the very deplorable condition he was in, and, in the sense of his calamities, still prays that God would graciously appear for him against his persecutors,

I will be glad and rejoice in thy mercy. For mercy past he is grateful, and for mercy future, which he believingly anticipates, he is joyful. In our most importunate intercessions, we must find breathing time to bless the Lord: praise is never a hindrance to prayer, but rather a lively refreshment therein. It is delightful at intervals to hear the notes of the high sounding cymbals when the dolorous sackbut rules the hour. Those two words, glad and rejoice, are an instructive reduplication, we need not stint ourselves in our holy triumph; this wine we may drink in bowls without fear of excess. For thou hast considered my trouble. Thou hast seen it, weighed it, directed it, fixed a bound to it, and in all ways made it a matter of tender consideration. A man's consideration means the full exercise of his mind; what must God's consideration be? Thou hast known my soul in adversities. God owns his saints when others are ashamed to acknowledge them; he never refuses to know his friends. He thinks not the worse of them for their rags and tatters. He does not misjudge them and cast them off when their faces are lean with sickness, or their hearts heavy with despondency. Moreover, the Lord Jesus knows us in our pangs in a peculiar sense, by having a deep sympathy towards us in them all; when no others can enter into our griefs, from want of understanding them experimentally, Jesus dives into the lowest depths with us, comprehending the direst of our woes, because he has felt the same. Jesus is a physician who knows every case; nothing is new to him. When we are so bewildered as not to know our own state, he knows us altogether. He has known us and will know us: O for grace to know more of him! "Man, know thyself, "is a good philosophic precept, but "Man, thou art known of God, "is a superlative consolation.

Thou hast known my soul in adversities - When all forsook me; when none could help me; when I could not save my own life; when my enemies were sure that I could not escape; then I found thee to be my Friend and Supporter. When friend, so called, finds it convenient not to know his friend in affliction and poverty, then thou didst acknowledge me as thine own, all worthless as I was. Human friendships may fail; but the Friend of sinners never fails. Cicero defines a real friend, Amicus certus in re incerta cernitor: “A friend in need is a friend indeed.” Reader, such a Friend is the Lord.

I will be glad and rejoice in thy mercy - I will triumph and joy in thy mercy; that is, in the mercy which he had already experienced, and in that which he still hoped to enjoy. He had had abundant proofs of that mercy; he hoped for still further proofs of it; and he says that he would find his joy in that, and not in what idols could give. For thou hast considered my trouble - In times past and now. He felt assured that his prayer would be regarded, and that God would relieve and deliver him. Thou hast known my soul in adversities - In the troubles that have come upon me. That is, God had seen and known all the feelings of his heart in the time of adversity; his sorrow and anxiety; his hope and trust; his uncomplaining spirit; his feeling of entire dependence on God, and his belief that He would interpose to save him. God had not turned away from him, but had shown that he regarded with interest all his feelings, his desires, his hopes. It is much, in the time of trouble, to know that all our feelings are understood by God, that He sees all our sorrows, and that He will not be regardless of them. There are no states of mind more interesting than those which occur in adversities; there is no one who can fully understand the soul in adversities but God; there is no one but God who can entirely meet the needs of the soul in such seasons.
