Charles H. Spurgeon on Psalms 20:2

"Send thee help from the sanctuary." Here we see the nature of true faith, that it causeth us to see help in heaven, and so to pray for it when there is none to be seen in the earth. And this is the difference between faith and unbelief; that the very unbelievers can by reason conceive of help, so long as they have any means to help them; but if they fail they can see none at all; so they are like unto those that are purblind, who can see nothing but near at hand. But faith seeth afar off, even into heaven, so that it is "the evidence of things that are not seen;" for it looketh unto the power of God, who hath all means in his hand, or can work without them, who made all of nothing, and "calleth the things that be not, as though they were." So that as the holy martyr Stephen, when his enemies were ready to burst for anger, and gnash at him with their teeth, looked steadfastly into heaven, and saw Christ standing at the right hand of God ready to defend him; so faith in the promises of the word doth see help in heaven ready for us, when there are no means in earth, —Nicholas Bownd.
