"Take this rule: whatever weakens your reason, impairs the tenderness of your conscience, obscures your sense of God, or takes off your relish of spiritual things; in short, whatever increases the strength and authority of your body over your mind, that thing is sin to you, however innocent it may be in itself." -- Susanna Wesley (Letter, June 8, 1725)
The last line is the kicker in this one.
We all have an idea in our minds of what sin is. We're familiar with the "big 10" and most of us do a pretty good job on a daily basis of not killing anyone or stealing.
But what about those seemingly "innocent" things? We rationalize that "it's just a book" or "just a TV show" or "just food". We say things that are "just words".
I wonder sometimes what it would be like to have a God that you could see in day to day life (kind of reminiscent of "The Shack"). Would we really do the things we do and say the things we say if we could see Him in the room with us? I'm pretty sure that suddenly some things would seem very wrong to us. Maybe even sinful...
