In “A (Very) Brief, Gospel-Centered Defense against the Problem of Evil,” Derek Rishmawy explains how we can know, through the Gospel, that God is indeed all-powerful, all-good, and all-knowing, despite the existence of evil:
If God raised Jesus Christ from the dead, I have good reason to believe both that he exists, and that he is unfathomably powerful.
Furthermore, if he is good enough to send his only-begotten Son to die on behalf of a sinful, rebellious world he loves, he is unfathomably good.
Next, if God is wise enough to use what is objectively the most horrifying, and initially apparently pointless, event in human history—the unjust murder of the Godman—for the salvation of the world, then it is entirely reasonable to trust he has a good enough reason for allowing the evil that he currently does.
Finally, the death and resurrection of Jesus Christ are the promise that ultimately evil will be judged, removed, and made right. There is comfort and hope for the future.
I love this. Read the rest of his post.
