And mind this one thing, prescribe nothing to God. If thou hast begun to wait, faint not, give not up, wait on still. It were good reason, were it but upon little hope at length to find Him: but since it is upon the unfailing assurance, that in the end thou shalt obtain, what folly were it, to lose all for want of waiting a little longer! See Psalm 40:1 In waiting  I waited-waited, and better waited- but all was over paid: He did hear me. So Psalm 130, I wait and wait until the morning. These two joined are all, and may well go together, earnest desire and patient attendance.

Robert Leighton (Archbishop of Glasgow, 1611 – 1684)
