In the day when I cried thou answerest me. No proof is so convincing as that of experience. No man doubts the power of prayer after he has received an answer of peace to his supplication. It is the distinguishing mark of the true and living God that he hears the pleadings of his people, and answers them; the gods hear not and answer not, but Jehovah's memorial is —"the God that heareth prayer." There was some special day in which David cried more vehemently than usual; he was weak, wounded, worried, and his heart was wearied; then like a child he "cried", —cried unto his Father. It was a bitter, earnest, eager prayer, as natural and as plaintive as the cry of a babe. The Lord answered it, but what answer can there be to a cry? —to a mere inarticulate wail of grief? Our heavenly Father is able to interpret tears, and cries, and he replies to their inner sense in such a way as fully meets the case. The answer came in the same day as the cry ascended: so speedily does prayer rise to heaven, so quickly does mercy return to earth. The statement of this sentence is one which all believers can make, and as they can substantiate it with many facts, they ought boldly to publish it, for it is greatly to God's glory. Well might the Psalmist say, "I will worship" when he felt bound to say "thou answeredst me." Well might he glory before the idols and their worshippers when he had answers to prayer to look back upon. This also is our defence against modern heresies: we cannot forsake the Lord, for he has heard our prayers. And strengthenedst me with strength in my soul. This was a true answer to his prayer. If the burden was not removed, yet strength was given wherewith to bear it, and this is an equally effective method of help. It may not be best for us that the trial should come to an end; it may be far more to our advantage that by its pressure we should learn patience. Sweet are the uses of adversity, and our prudent Father in heaven will not deprive us of those benefits. Strength imparted to the soul is an inestimable boon; it means courage, fortitude, assurance, heroism. By his word and Spirit the Lord can make the trembler brave, the sick whole, the weary bright. This soul might will continue: the man having been strengthened for one emergency remains vigorous for life, and is prepared for all future labours and sufferings; unless, indeed, he throw away his force by unbelief, or pride, or some other sin. When God strengthens, none can weaken. Then is our soul strong indeed when the Lord infuses might into us.
