Persistant Prayer

Ex 33:18 And he said, "Please, show me Your glory."

Again in our devotions Spurgeon says:

Refer to the thirteenth verse of this chapter, where Moses speaks to God:  "Now therefore, I pray, if I have found grace in Your sight, show me now Your way, that I may know You and that I may find grace in Your sight. And consider that this nation is Your people."
This is the true manner of prayer.  Do not be content with past answers, but double your request and ask again.  Nothing pleases God as much as when a sinner comes again with twice as large a petition:  "Lord, you heard me last time, and now I come again."  Faith is a mighy grace and always grows upon that which it feeds.
When God has heard prayer for one thing, faith comes and asks for two things, and when God has given those two things, faith asks for six.
Faith can scale the walls of heaven.  She is a giant grace.  She takes mountains by their roots and puts them on other mountains and so climbs to the throne in confidence with large petitions, knowing that she shall not be refused.  Most of us are too slow to go to God.  If we have been heard once, we go away instead of coming again and again, and each time with a larger prayer. 
Make your petitions longer and longer.  Ask for ten, and if God gives them, thenfor a thousand, and keep going util at last you will have enough faith to ask as great a favor as Moses did,  I beseech you, show me your glory."
