(Disclaimers: first, this is an outdoor only activity; second, is an athlete to carry a box of tissues?)
Had a college buddy with an old heather-gray t-shirt picturing a right index finger depressed right nostril football player. Not like Santa "laying his finger aside his nose" gently, but a nose hole pressed shut. One clamped down so the other can inflate a monstrous balloon of... snot. Yes, snot.
The shirt read, "Snot bubble. No trouble." Guy humor.
I'm an exceptionally nasaled fella. I know. Given the need a sufficient clamp & a stout blow makes the method work as advertised on my buddy's tee.
Snot bubble. No trouble. Press & blow.
So here I go... Another morning. Another run. Another nasal need. Another press & blow. A new revelation.
"If we confess our sins he is faithful & just & will forgive our sins & purify us from all unrighteousness," 1 John 1:9 states. An old truth.
Sin stumble. No trouble. Pray & ask.
