"And it shall come to pass that whosoever shall call on the name of the Lord shall be delivered." (Joel 2:32)
"...I need not ask whether I may call on Him or not, for that word 'whosoever' is a very wide and comprehensive one. Whosoever means me, for it means anybody and everybody who calls upon God. I will therefore follow the leading of the text, and at once call upon the glorious Lord who has made so large a promise.
My case is urgent, and I do not see how I am to be delivered; but this is no business of mine. He who makes the promise will find ways and means of keeping it. It is mine to obey His commands; it is not mine to direct His counsels. I am His servant; not His solicitor. I call upon Him, and He will deliver." (C.H. Spurgeon)
