When I go out for a run, I am tired at the end of it. Soon afterwards I can run further and faster.
When I go to the gym I am sore and weak at the end of it. Soon afterwards I can lift greater weights.
When I spend hours drawing I am worn out. The next time I draw I’m even better.
When I study with intense concentration, I get tired and distractable. I’ll do even better on the test.
When I engage someone in debate I walk away tired, but by the next day I’m even more prepared.
This is the way life works. We are challenged, we grow weary, we come back stronger. That’s all around us in almost everything we do. It is ever the same with temptation.
And note what that says about God’s grace. Yes, He helps us fight, but more importantly He gives us the chance to rest so we can come back stronger. The devil, for all his faults, is still stronger than us. Satan could likely tempt everyone who has ever lived for every second of their lives and not break a sweat. That doesn’t happen because God pushes him back so we have the chance to rest, grow, and learn.
