His Steadfast Love Endures Forever

God's steadfast love endures forever is the refrain in all 26 verses of Psalm 136. But how do we know? What proof does the psalmist give?

God is good. He is the God of gods and Lord of all lords.
God is powerful.
God serves us in mighty, even miraculous ways.
God is the Creator. He made things with understanding, with care and divine forethought. Everything is on purpose - the land, the water, the lights, the darkness.
God works justice for His people.
God delivers, redeems, protects, guides, and governs His people.
God removes unrighteous rulers.
God rewards His children and gives them an inheritance.
God considers our frame, our weakness and iniquity, and still He rescues us. He sent His Son to live perfectly for us, to die in our place, and to raise to give us freedom. He has rescued us from our biggest foes - sin, death, the devil. 
God gives us all that we need.

All these God did for the Israelites. Yet the refrain says, his steadfast love endures forever. So we can be sure He is still and will continue to do these things for us as well.

26 Give thanks to the God of heaven,
for his steadfast love endures forever.
