The Duty of Singing Psalms LOUDLY.

"And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them" (Acts 16:25).

This proves that the singing of psalms is a gospel ordinance, and ought to be used by all good Christians; and that it is instituted, not only for the expressing of their joys in a day of triumph, but for the balancing and relieving of their sorrows in a day of trouble. It was at midnight that they sang psalms, according to the example of the sweet psalmist of Israel (Ps. cxix. 62): At midnight will I rise to give thanks unto thee. (3.) Notice is here taken of the circumstance that the prisoners heard them. If the prisoners did not hear them pray, yet they heard them sing praises. [1.] It intimates how hearty they were in singing praises to God; they sang so loud that, though they were in the dungeon, they were heard all the prison over; nay, so loud that they woke the prisoners: for we may suppose, being at midnight, they were all asleep. We should sing psalms with all our heart. The saints are called upon to sing aloud upon their beds, Ps. cxlix. 5. But gospel grace carries the matter further, and gives us an example of those that sang aloud in the prison, in the stocks. [2.] Though they knew the prisoners would hear them, yet they sang aloud, as those that were not ashamed of their Master, nor of his service. Shall those that would sing psalms in their families plead, in excuse for their omission of the duty, that they are afraid their neighbours should hear them, when those that sing profane songs roar them our, and care not who hears them?
