1 Samuel 12:23
Moreover as for me, God forbid that I should sin against the LORD in ceasing to pray for you…
The sainted Robert Murray M'Cheyne wrote to his church at Dundee, during his last illness: "You have hindered God's work by your want of prayer. When God gives grace to souls, it is in answer to the prayers of His children...When God puts it into the hearts of His children to pray, it is certain that He is going to pour down His spirit in abundance...The salvation of those around you depends upon your asking...I often think it strange that ever we should be in heaven, and so many in hell through our soul-destroying carelessness...Plead and wrestle with God, showing Him that the cause is His own, and that it is all for His own glory to arise and have mercy upon Zion."
