" '...the LORD gives you in the evening meat to eat and in the morning bread to the full, because the LORD has heard your grumbling that you grumble against him...Come near before the LORD, for he has heard your grumbling.' ...And the LORD said to Moses, 'I have heard the grumbling of the people of Israel. Say to them, "At twilight you shall eat meat, and in the morning you shall be filled with bread. Then you shall know that I am the LORD your God."'" (Exodus 16:8-12)
If this was God's response to grumbling...how might He have responded to a faith-filled plea for provision? If He invited a group of complaining whiners to come near to Him and rained down miraculous food for them to eat...what might He have done for a people who praised and thanked Him and then asked Him to meet their needs and trusted (based on very recent experience!) that He would??
He is so merciful and generous, even when we are unbelieving, petulant children...but O, that I would remember His character and deeds and ASK Him for help from a place of gratitude and trust, rather than grumble in unbelief, convinced that He won't provide what I need!
What We Forget; What He Forgets
