Bible Notes Online - Psalms 116 - ESV
Commentary

Consecration to God; simple words, demonstrating a deep personal gratitude; the psalmist is overwhelmed by God's goodness to him.

v1-2: The God who answers prayer, even from an individual; the psalmist is making personal statements; I, my, me. He hears the penitent sinner pleading for mercy. And we love Him because He first loved us.

v3-4: The terrors of sin drag the soul towards death, and only God can deliver. The words here refer to being at the death's door. Whatever our circumstances, we can find deliverance.

But, praise God, He can deliver. Again; I, my, me; the words are genuine and from the heart.

v5-7: Simple testimony to the character of God, and personal gratitude that God intervened, "He saved me." His soul can be at rest, for God has stepped in in power and grace.

v8: Delivered, or saved; this is God's work in our lives.

v9: We are delivered from something v8), and delivered into something, that is a life of obedience.

v10-11: Testimony of personal suffering. Sometimes such circumstances lead to hasty words, which may be unwise or untrue.

v12-14: The response of gratitude, 'What more can I do?' He is worthy, therefore I will give Him my life; such is the response of the grateful heart.

'I will fulfil my vows to the Lord."  here is testimony and accountability; encouragement and provocation. The Psalmist is living his life in community - he fulfils thse vows 'in the presence of all his people.'

v15: Even in death God will remember His own.

v16: Commitment to a life of submission.

v17-19: There is a place for worship and submission, and that is amongst God's people. Even though this psalm is very personal, it ends with the psalmist seeking fellowship with like minded people.
