I have had more trouble with myself than with any other man. – D.L. Moody
Yes, we are many times our biggest problem. The constant decisions of right vs. wrong and living with the consequences.
We all have a moral compass, it’s just that some choose to ignore it. Unfortunately, the more you do something, the more you become numb to it. There are few regrets for doing the right thing. There are always regrets for doing wrong, either now or down the road.
Even if you escape it in the temporal world (while you are living), there are consequences in the Eternal world (your soul).
Moody was a biblical scholar and he refers to all of the above. He is worth reading up on as he was a wise person, but still fought with himself and his struggle on Earth.
