Hello, it is because issues have been raised since mankind’s creation: Can humans be successful without God leadership? With enough time being given the question can clearly be answered and God must publish worldwide the results called judgments.
Ecclesiastes 8:9-10
Living Bible
9-10 I have thought deeply about all that goes on here in the world, where people have the power of injuring each other. I have seen wicked men buried, and as their friends returned from the cemetery, having forgotten all the dead man’s evil deeds, these men were praised in the very city where they had committed their many crimes! How odd!
