No time or place where prayer is not acceptable unto God, and prevalent with him; nay, it sounds the sweeter when on the waters of affliction a good man pours it forth unto God. Sang praises unto God, that they were counted worthy to suffer for Christ: and being all things are overruled for the good, and conduce to the advantage, of them that love God, Romans 8:28, they owe unto God thanks for all things through Jesus Christ, which is also required of them, Ephesians 5:20.
