Therefore humble yourselves under the mighty hand of God, that he may exalt you in due time, casting all your care upon Him, for He cares for you. - 1 Peter 5:6-7
Here God is telling us that one of the most important weapons - one of the greatest benefits - He has given us to resist Satan’s attacks upon our joy and peace and intimacy with God is to stop trying to solve every problem that comes our way in OUR OWN STRENGTH; BY OUR OWN POWER; BY OUR OWN MEANS. Give it to God instead! Give HIM our burden! Include Him in it, for deliverance if necessary ... for provision if necessary ... for whatever wisdom might dictate in the situation.
I mean … think about it. If He didn’t want us giving Him our troubles – giving Him our adverse cares – why would He tell us to do so in the first place? He tells us so we'll be wise enough to do it!
That's why I so love this song by Amy Grant. Sums it all up so beautifully.
