The fifty-fourth Psalm bears an inscription that would refer it to this occasion. There are some expressions in the psalm that hardly agree with this reference; but the general situation is quite in keeping with it. "Save me, O God," the Psalmist cries, "by Thy name, and judge me by Thy strength." The danger from which he needs to be saved comes from strangers that are risen up against him, and opposers that seek after his soul; persons "that have not set God before them." To be saved by God's _name_ is to be saved through attributes which are manifestly Divine; to be judged by God's _strength_, is to be vindicated, to be shown to be under God's favour and protection, by the manifest exercise of His power. The petitions are such as David might well have made after his conversation with Jonathan. The psalm is evidently the song of one whose hand had been "strengthened in God." Its great central truth is, "God is mine helper; the Lord is with them who (like Jonathan) uphold my soul." And there comes after that a happy exercise of the spirit of trust, enabling the Psalmist to say, "He hath delivered me out of all trouble." This result is wonderful and beautiful. How remarkable that in that wilderness of Judah, amid a life of hardship, exposure, and peril, with a powerful king thirsting for his blood, and using his every device to get hold of him, he should be able to say of God, "He hath delivered me out of all trouble." It is the faith that removes mountains: it is the faith that worked so wonderfully when the lad with the sling and stones went out so bravely against the giant. What wonders cannot faith perform when it gets clear of all the entanglements of carnal feeling, and stands, firm and erect, on the promise of God! How infinitely would such a faith relieve and sustain us in the common troubles and anxieties of life, and in deeper perplexities connected with the cause of God! Take this short clause as marking out the true quality and highest attainment of simple faith, and resolve that you will not rest in your own endeavours till your mind reaches the state of tranquillity which it describes so simply,--"He hath delivered me out of all trouble."
