We must sometimes pray that we may pray, and when as we are apt to judge ourselves that we are most unfit to pray, then to pray that we may become fit to pray; as by speaking, men are fitted to speak; by running to run; by wrestling to wrestle; by laboring to labor.
When Christ by His Spirit calls us to Him, puts us upon asking, and when He stands still waiting to be gracious to us, let Him not go till He bless us.
Prayer is a spiritual and faithful opening of the heart to God in the name of Christ with an eye to seasonable help and relief from Him. By heart, we mean thoughts, desires, affections; these wants and weak-nesses and sins to which the heart is privy and of which it is sensible.
The work of prayer is not to move or remove God—He is in one mind, He is still the same—but to move and remove our hearts near to the Lord; and then have we prayed to purpose when by prayer our hearts and spirits are in a more sublime and celestial frame; when we are more above natural, carnal, and formal self; when more off and above the world and all the encouragements and discouragements of it.
