...if the Apostle Paul said it TWICE:
I Corinthians 6:12
All things are lawful unto me, but all things are not expedient: all things are lawful for me, but I will not be brought under the power of any.
I Corinthians 10:23
All things are lawful for me, but all things are not expedient: all things are lawful for me, but all things edify not.
What are you doing today that isn't a "sin",
but it also isn't "expedient" (useful; profitable)?
What are you participating in today that may be "ok" for you to do,
but it does not edify (to build)?
What are you allowing in your life today that may be "ok" for others,
but you have come "under" (a state of oppression or subjection to) its power?
One important truth:
If it's a sin - don't do it!
If it isn't a sin - is it useful? are you under its power? does it build you as a Christian?
Good questions for us today!
