Because God himself will strengthen us
“Behold, God is my salvation; I will trust, and will not be afraid; for the Lord God is my strength and my song, and he has become my salvation.” IS 12.2
Fear not, for I am with you; be not dismayed, for I am your God; I will strengthen you, I will help you, I will uphold you with my righteous right hand. IS 41.10
We don’t have to somehow summon up strength from within ourselves. If you don’t think you have the strength to make it through, well, you’re absolutely right. You don’t. We don’t have the strength to part the Red Sea or be cheerful in the midst of kids melting down, but God does. And he will pour his strength into us.
When you look down from the edge of the cliff, it looks like a long, long fall. Take courage, you’re tied to an almighty immovable Tree. Don’t worry if you’ll have enough courage for tomorrow. God will give you all the strength you need for today. And he’s got bags and bags of grace stored up for tomorrow, a whole warehouse of grace stored up for the future.
