The Bible does not take us as far as we might like to go into the mysteries it contains. Rather it says, “The secret things belong to…God.” The heart of the Bible and the heart of Christianity is not an explanation of where evil came from, but a demonstration of how God enters into it and turns it for the very opposite — everlasting righteousness and joy.
–John Piper
God doesn’t give us all the answers we want. But he does give us all of the answers we need.
It is not extremely important for us to know the full explanation of where evil came from.
But it is important for us to know what we are to do about evil – allow God to enter into the midst of our sin and evil and pain and suffering and turn all of it into everlasting righteousness and joy.
No matter what you are struggling through the midst of right now, know that God is there with you and can turn it in such a way that it will bring glory to Him. Trust Him in the midst of it to take your hand and walk you through it such that you may never get an answer to “Why” but you will understand the answer to “To What End?” and “For What Purpose?” as He shows you how He can use your experience to bring more glory to His Great Name.
