Psalm 107

"Then in their trouble they called to the LORD, and he saved them from their distress." Four times through this psalm this phrase is repeated (vss 6, 13, 19, & 28). This followed a description of their circumstances in their exile. In each case God responded to their pleas in ways that satisfied their needs while strengthening their faith. His actions answered their prayers; not only provided delivery but also giving them the opportunity to give God thanks; for his wonderful deeds and his constant love.
