How to properly construct a "Pay Back" - Psalms 114-116

Psalm 116:12 - "What shall I render to the for all His benefits toward me? The Psalmist asks a great question in this verse. How to you "pay back" God for all the benefits He has provided? How do you convey what all those benefits mean to us? I suppose the first step is to identify all of those benefits. We, at times, forget to "count" our many blessings and name them "one by one" as the old hymn states. Before he states this verse, the writer actually lists several of those benefits, 1). He hears us (v. 1); 2). God is gracious, righteous and compassionate toward us (v. 5). 3). God "preserves" us (v. 6). 4). Rescues our soul from death, our eyes from tears and our feet from falling (v. 8). 5). Accompanies us (v. 9). With so many benefits what shall we render to God? The writer actually answers that question in the next line: "I shall lift up the cup of salvation and call upon the name of the Lord." The Psalmist states that the way to "render" to God for all His benefits is to lift up the "cup of salvation and call upon the name of the Lord." So, to "pay back" we are "lift up" the cup of salvation. What does that mean? Matthew Henry commentary states the following in regard to the cup: The pious Jews had sometimes a cup of blessing, at their private meals, which the master of the family drank first of, with thanksgiving to God, and all at his table drank with him. But some understand it not of the cup that he would present to God, but of the cup that God would put into his hand I would agree with the latter version of it. I believe we are to offer up what God has saved, the cup of salvation is us. He has saved us. The second line of the Hebrew poetry says I will "call upon the name of the Lord." This is highly personal language. I think what the writer is saying is that he will render to God himself and continue to allow God to rescue and save him. That is the way we render to God praise and render "pay back" for what He has done for us. We are not to think we get this salvation from God and then go on our marry way, saying a few thank you verses over our shoulder. We are to be like the leper in the story of the ten lepers in Luke 17. Only one came back to offer himself in thanksgiving. The others were too busy rejoicing over their "cleansing". In says in 17:15 that "one of them, when he saw that he had been healed, 'turned back', glorifying God with a loud voice. I think that is what the Psalmist means when he says "lift up the cup of salvation." He has just expressed the same thought in the verses preceeding. This is his summary "big idea". Lift up the cup of salvation (yourself) and offer yourself to God in praise for all His benefits.
