What shall I repay to the Lord For all His benefits to me? 13 I will lift up the cup of salvation, And call upon the name of the Lord. 14 I will pay my vows to the Lord; May it be in the presence of all His people! 15 Precious in the sight of the Lord Is the death of His godly ones.
-- Psalm 116:12-15
This person is being clear that he feels he owes God something. He received something from the Lord and receiving it calls for offering something in kind. The question is, what can you offer the God who owns everything? The only thing you can offer is your allegiance, and he does. What can I give you, to repay you, I can give you all of me. When we do this, we become a child of the King, a joint heir with Jesus. Your gift to God, to repay him, is returned again, and much more than what you got first. The truth is God will always out give you, every day, all day.
I shall walk before the Lord In the land of the living. 10 I believed when I said, “I am greatly afflicted.” 11 I said in my alarm, “All people are liars.”
-- Psalm 116:9-11
Sometimes we doubt God for a season, but as he proves true again and again, our doubt turns to trust. Our experience may be that all men are liars, and that is sad, but our hope lies in Jesus and not in the world. We can say to those liars, and the good people if we find them, that God is faithful, and he will bring us to himself over the efforts of the world and the devil.
For the Lord has dealt generously with you. 8 For You have rescued my soul from death, My eyes from tears, And my feet from stumbling. Return to your rest, my soul,
-- Psalm 116:7-8
In spite of what people say, in my opinion it is good to talk to yourself. The guy in this Psalm is doing that. He is saying to himself, “Remember God has been good to you, and his rescue has put you in a good place, when you could only see death coming.” Praise must start with acknowledging to yourself how you have been saved, and how it was undeserved. We often times are telling ourselves the opposite, like how we deserve more and we have been cheated. If that is what you are telling yourself, you will seldom get around to praise God for all his mercies and grace.
