One of the most consistent plaints I hear against God is why does he allow suffering? Many answers have been offered, but one that has not been mentioned much is one that occurred to me not too long ago. It is, in some ways, a result of the gift of free will that He granted to us, but too often, because we are often lazy, it is one that is not quickly valued. But I consider it an extremely valuable gift.
Simply put, God allows us to suffer because God respects us. He respects us enough that He allows us to make our own choices, including the bad ones. (NOTE: This doesn’t cover suffering that is not caused by your actions.)
And because He sees opportunity where we see just suffering. (NOTE: This part does cover suffering that is not caused by your own actions.)
