Use it or lose it applies in, as far as I can tell, every situation. But what I’ve learned from those aging gracefully is there is no need to tell them that “no pain, no gain” is just bunk.
Muscle tone: the resting tension in a muscle. It’s not just about buff, cut, or 6-pack abs. Tone comes from effort, preparing muscles so we are ready to respond without delay.
The little ones who cling and cooperate
who listen to instructions
who raise their hands
and smile to answer questions…
They fill you up and keep you coming back.
They’ll do fine.
The ones who resist and refuse
who defy you to “make them”
who turn a cold shoulder or don’t turn at all
and scowl when you call on them…
These sap your strength and make you wonder why you tried.
They are the reason you came.
I tell you that in the same way there will be more rejoicing in heaven over one sinner who repents than over ninety-nine righteous persons who do not need to repent. ~ Luke 15:7
