Several years ago my Grandma was injured when she leaned against the railing on her back porch, and it snapped like a twig, sending her several feet down to the ground. The railing had rotted through and gave way the moment she put her weight on it.
She had leaned on something that simply couldn't hold her up.
"Trust in the LORD with all your heart, and do not lean on your own understanding" (Proverbs 3:5). We've read it a million times, but have we considered why we aren't supposed to lean on our own understanding?
Because it's flimsy. And it just plain cannot hold us up.
And yet we do it, don't we? We operate on assumptions we make based on what we feel, and we make decisions based on what we perceive our circumstances to be. But our small, limited understanding of things is flimsy.
"I have nothing on my calendar and see nothing on the horizon."
"There's no way these bills are going to get paid."
"I'm over this relationship--it's never going to change. I'm done."
It's tough to lean on something other than what we can see. It's not easy to operate on faith, but the One in whom we have faith is a strong tower, a firm foundation. "Do not lean on your own understanding." It just can't hold you up.
But He will.
