You have been unable to trust God to give you day by day your daily bread, and therefore you have been craving for what you call “some provision for the future.” You want a more trusty provider than providence, a better security than God’s promise. You are unable to trust your heavenly Father’s word, a few bonds of some half bankrupt foreign government you consider to be far more reliable; you can trust the Sultan of Turkey, or the Viceroy of Egypt, but not the God of the whole earth!
In a thousand ways we insult the Lord by imagining “the things which are seen” to be more substantial than his unseen omnipotence. We ask God to give us at once what we do not require at present, and may never need at all; at bottom the reason for such desires may be found in a disgraceful distrust of him which makes us imagine that great stores are needful to ensure our being provided for. Brethren, are you not to blame here, and do you expect the Lord to aid and abet your folly? Shall God pander to your distrust? Shall he give you a heap of cankering gold and silver for thieves to steal, and chests of garments to feed moths? Would you have the Lord act as if he admitted the correctness of your suspicions and confessed to unfaithfulness? God forbid!
Expect not, therefore, to be heard when your prayer is suggested by an unbelieving heart: “Commit thy way unto the Lord; trust also in him and he shall bring it to pass.”
From a sermon by Charles Haddon Spurgeon entitled “The Conditions of Power in Prayer,” delivered March 23, 1873.
