Charles H. Spurgeon on Psalms 91:3

Surely he shall deliver thee from the snare of the fowler. Assuredly no subtle plot shall succeed against one who has the eyes of God watching for his defence, We are foolish and weak as poor little birds, and are very apt to be lured to our destruction by cunning foes, but if we dwell near to God, he will see to it that the most skilful deceiver shall not entrap us.

"Satan the fowler who betrays

Unguarded souls a thousand ways," shall be foiled in the case of the man whose high and honourable condition consists in residence within the holy place of the Most High.

And from the noisome pestilence. He who is a Spirit can protect us from evil spirits, he who is mysterious can rescue us from mysterious dangers, he who is immortal can redeem its from mortal sickness. There is a deadly pestilence of error, we are safe from that if we dwell in communion with the God of truth; there is a fatal pestilence of sin, we shall not be infected by it if we abide with the thrice Holy One; there is also a pestilence of disease, and even from that calamity our faith shall win immunity if it be of that high order which abides in God, walks on in calm serenity, and ventures all things for duty's sake. Faith by cheering the heart keeps it free from the fear which, in times of pestilence, kills more than the plague itself. It will not in all cases ward off disease and death, but where the man is such as the first verse describes, it will assuredly render him immortal where others die; if all the saints are not so sheltered it is because they have not all such a close abiding with God, and consequently not such confidence in the promise. Such special faith is not given to all, for there are diversities in the measure of faith. It is not of all believers that the psalmist sings, but only of those who dwell in the secret place of the Most High. Too many among us are weak in faith, and in fact place more reliance in a phial or a globule than in the Lord and giver of life, and if we die of pestilence as others die it is because we acted like others, and did not in patience possess our souls. The great mercy is that in such a case our deaths are blessed, and it is well with us, for we are for ever with the Lord. Pestilence to the saints shall not be noisome but the messenger of heaven.
