Charles H. Spurgeon on Psalms 55:16

As for me, I will call upon God. The psalmist would not endeavour to meet the plots of his adversaries by counterplots, or imitate their incessant violence, but in direct opposition to their godless behaviour would continually resort to his God. Thus Jesus did, and it has been the wisdom of all believers to do the same. As this exemplifies the contrast of their character, so it will foretell the contrast of their end —the righteous shall ascend to their God, the wicked shall sink to ruin. And the Lord shall save me. Jehovah will fulfil my desire, and glorify himself in my deliverance. The psalmist is quite sure. He knows that he will pray, and is equally clear that he will be heard. The covenant name is the pledge of the covenant promise.
