Psalm 107:6, 13, 19, 28 Then they cried unto the Lord in their trouble, and he delivered them.
This refrain is spoken four times in this Psalm. The truth is repeated because the problem (trouble) and the solution (delivered) is repeated many times in the life of the people. From the beginning of their salvation at the Exodus, through the wilderness wandering, after the conquest of the Land, and to the present day, the cycle is repeated: sin, trouble, crying out, and deliverance.
So it is in our life, too, when we analysis it Biblically. Over and again, our sin causes trouble and distress, we pray when we are in trouble, and the Lord hears, answers and delivers. The Christian, being both saint and sinner at the same time, lives within this pattern weekly and daily. We don’t see precisely how this pattern works itself out or where we are in the cycle, for we are always sinners, always in trouble, always praying, and always being saved, with all four parts working at the same time. So we pray without ceasing, repent and believe daily, and always live in the peace, love and joy of the Lord.
