Deut. 8:10, 17-18
“When you have eaten and are satisfied, praise the LORD your God for the good land He has given you…But remember the LORD your God, for it is He who gives you the ability to produce wealth, and so confirms his covenant, which he swore to your forefathers…” NIV
In Deuteronomy 8, God warned his people not to forget that it was by His hand of blessing that they were able to enjoy their prosperity. It is an interesting paradox that people will cry out to God for help when they are having financial problems and then forget about Him when things are going well.
