Deuteronomy 8:18

And you shall remember the Lord your God, for it is He who gives you power to get wealth, that He may establish His covenant which He swore to your fathers, as it is this day.

God made of a covenant with Abraham, which we receive the benefit from when we accept Jesus as our savior.  That is why we need to remember God and thank Him for all the blessings that came down to us through Jesus.  Without this covenant, we would not have the power to get wealth, healing, guidance, and protection.
