Charles H. Spurgeon on Psalms 116:14

I will pay my vows unto the Lord now in the presence of all his people. The Psalmist has already stated his third resolution, to devote himself to the worship of God evermore, and here he commences the performance of that resolve. The vows which he had made in anguish, he now determines to fulfil: "I will pay my vows unto the Lord." He does so at once, "now, "and that publicly, "in the presence of all his people." Good resolutions cannot be carried out too speedily; vows become debts, and debts should be paid. It is well to have witnesses to the payment of just debts, and we need not be ashamed to have witnesses to the fulfilling of holy vows, for this will show that we are not ashamed of our Lord, and it may be a great benefit to those who look on and hear us publicly sounding forth the praises of our prayer hearing God. How can those do this who have never with their mouth confessed their Saviour? O secret disciples, what say you to this verse! Be encouraged to come into the light and own your Redeemer. If, indeed, you have been saved, come forward and declare it in his own appointed way.
