“as thy days, so shall thy strength be” [Deuteronomy 33:25]

“as thy days, so shall thy strength be”. So it is not a matter of how long your strength will last, but that God will give you strength enough for today.
The Lord gives us life a day at a time – you may plan for tomorrow and if those plans work out, look to the Lord for needed strength.
So while you may feel weak and inadequate for the new challenge set before you, it is strength for today that is all you need today. Strength is something you use, not that you store up. If you are waiting for a week’s strength before doing a day’s work you are likely to be missing out on opportunities set before you.
Best of all, the Lord knows just what you need and he will provide. It is a daily drawing of strength we need to make. [AP]
