2. He resolves to delight and triumph in God notwithstanding; when all is gone his God is not gone (v. 18): "Yet will I rejoice in the Lord; I shall have him to rejoice in, and will rejoice in him." Destroy the vines and the fig-trees, and you make all the mirth of a carnal heart to cease, Hos. ii. 11, 12. But those who, when they were full, enjoyed God in all, when they are emptied and impoverished can enjoy all in God, and can sit down upon a melancholy heap of the ruins of all their creature comforts and even then can sing to the praise and glory of God, as the God of their salvation. This is the principal ground of our joy in God, that he is the God of our salvation, our eternal salvation, the salvation of the soul; and, if he be so, we may rejoice in him as such in our greatest distresses, since by them our salvation cannot be hindered, but may be furthered. Note, Joy in God is never out of season, nay, it is in a special manner seasonable when we meet with losses and crosses in the world, that it may then appear that our hearts are not set upon these things, nor our happiness bound up in them. See how the prophet triumphs in God: The Lord God is my strength, v. 19. He that is the God of our salvation in another world will be our strength in this world, to carry us on in our journey thither, and help us over the difficulties and oppositions we meet with in our way. Even when provisions are cut off, to make it appear that man lives not by bread alone, we may have the want of bread supplied by the graces and comforts of God's Spirit and with the supplies of them. (1.) We shall be strong for our spiritual warfare and work: The Lord God is my strength, the strength of my heart. (2.) We shall be swift for our spiritual race: "He will make my feet like hinds' feet, that with enlargement of heart I may run the way of his commands and outrun my troubles." (3.) We shall be successful in our spiritual enterprises: "He will make me to walk upon my high places; that is, I shall gain my point, shall be restored unto my own land, and tread upon the high places of the enemy," Deut. xxxii. 13; xxxiii. 29. Thus the prophet, who began his prayer with fear and trembling, concludes it with joy and triumph, for prayer is heart's ease to a gracious soul. When Hannah had prayed she went her way, and did eat, and her countenance was no more sad. This prophet, finding it so, publishes his experience of it, and puts it into the hand of the chief singer for the use of the church, especially in the day of our captivity. And, though then the harps were hung upon the willow-trees, yet in the hope that they would be resumed, and their right hand retrieve its cunning, which it had forgotten, he set his song upon Shigionoth (v. 1), wandering tunes, according to the variable songs, and upon Neginoth (v. 19), the stringed instruments. He that is afflicted, and has prayed aright, may then be so easy, may then be so merry, as to sing psalms.
