Now, what does that mean? It means any action that is not motivated and done by complete faith in God is sin. Anytime you do anything you’re not absolutely confident is God’s will for you to do, if you have a doubt about doing that thing, whether the thing in and of itself is right or wrong, you’ve sinned.
A man was in the back bedroom getting dressed. His wife was out in the living room talking with a friend. He yelled out, “Is this shirt clean enough for me to wear?” Without hesitation, she said “no” and went on talking.
After a while he came out, buttoning up another shirt. He asked, “How did you know that shirt wasn’t clean without looking at it?” She said, “If you had to ask, it wasn’t.”
Now, that’s what God is saying here: whatsoever is not of faith (that you don’t have confidence in) is dirty. If it’s doubtful, it’s dirty. Leave it alone.
Friend, we ought to give God the benefit of the doubt, and if we think it may be wrong, we should leave it alone until we’re sure that it is right.
