First Corinthians 10:13 is certainly a promise — but it isn’t talking about trials. It’s talking about temptation. The promise is that God will always, always give you the power to say no to sin. But when it comes to heartaches, physical problems, and disappointments — things out of your control, difficult circumstances suddenly thrust upon you — you may very well be overwhelmed beyond what you can bear. There is a kind of suffering that rips your world apart and leaves you bewildered and wounded. There are trials that overwhelm.
I drew a deep breath, showing my friend the context of the promise — and her brow furrowed. “But take heart,” I told her. “It’s when we are at the end of our strength . . . that’s when we fall helplessly into the everlasting arms of God. That’s when God floods our hearts with sustaining grace.”
