The Lord knows our bearing capacity, both as to coping and to comprehending, and He will not give us more to bear than we can manage at the moment, though to us it may seem otherwise. Just as no temptations will come to us from which we cannot escape or which we cannot bear, we will not be given more trials than we can sustain.
Don't fear, just live right.
We should not assume; however, that just because something is unexplainable by us, it is unexplainable.
