I've heard it said, "God promises He won't give you anything you can't handle," and wondered why good-intentioned people would so place the burden on themselves when nowhere in God's word is such a demand found.
God does promise us a way out of temptation, and temptation alone, but temptation, a matter of free will, is so different to suffering, which is out of our control completely.
In fact, Jesus promises us troubles, but tells us to be of good cheer, for He has overcome!
Paul tells us all who desire to live godly will suffer, and indeed, shares the suffering of both himself and his fellow ministers, who all despaired. Every obedient prophet suffered immensely, even unto death, for the glory of God, and many saints suffer unimaginable persecutions.
However, though never explaining the whys, He does give the same promise repeatedly: HE WILL BE THERE.
So- to the suffering, to the overcome, the weak, the grieving, the confused, the heavy-burdened, and the despairing, I remind you of this promise, even when you don't see or understand:
Rejoice, for it's not up to you at all! God won't ever give you anything HE can't handle!
And that's a promise.
NB: I'm not a 'Bible Scholar,' I've just read the Bible and listened and asked questions.
