If God is good why is there evil?
“The fact that humans used God-given free choice to disobey God did not take God by surprise. C. S. Lewis suggests that God in his omniscience 11 saw that from a world of free creatures, even though they fell, he could work out … a deeper happiness and a fuller splendor than any world of automata would admit.”” Or, as Geisler has put it so well, the theist does not have to claim that our present world is the best of all possible worlds, but it is the best way to the best possible world:
If God is to both preserve freedom and defeat evil, then this is the best way to do it, Freedom is preserved in that each person makes his own free choice to determine his destiny. Evil is overcome in that, once those who reject God are separated from the others, the decisions of all are made permanent. Those who choose God will be confirmed in it, and sin will cease. Those who reject God are in eternal quarantine and cannot upset the perfect world that has come about. The ultimate goal of a perfect world with free creatures will have been achieved, but the way to get there requires that those who abuse their freedom be cast out.”
A critically important factor involved in the suggestion that this may not be the best possible world but it is the best way to the best possible world is that God is not finished yet. Too often people fall into the trap of thinking that because God hasn’t dealt with evil yet, he is not dealing with it at all. My old colleague Walter Martin used to say, “I’ve read the last chapter in the book, and we win!” Evil will one day be done away with. just because evil is not destroyed right now does not mean it never will be.
In view of the above facts, the existence of evil in the world is seen to be compatible with the existence of an all-good and all-powerful God we can summarize the facts this way:
1. If God is all-good, he will defeat evil.
2. If God is all-powerful, he can defeat evil.
3. Evil is not yet defeated.
4. Therefore, God can and will one day defeat evil.”
One day in the future, Christ will return, strip away power from the wicked, and hold all men and women accountable for the things they did during their time on earth (see Matthew 25:31-46; Revelation 20:11-15). justice will ultimately prevail. Those who enter eternity without having trusted in Jesus Christ for salvation will understand just how effectively God has dealt with the problem of evil.”
