From my 2009 Journal. Do we have any rules we need to abide by as believers? Moses’ Law says “Don’t murder.” Jesus says it’s what’s in your heart that’s important. Is “don’t hate” a rule? I suppose you could say that. Rules generally govern actions, and hatred is not an action (unless it’s acted upon). But if you take care of the attitude (hatred) in your heart, you’ll have no temptation to do the action (murder).
We usually judge a person’s actions, though I have to say I’m guilty of judging a person’s heart based on their actions. I wouldn’t know what’s in their heart if I didn’t see their action.
Romans 14 refers to religious activity: eating meat offered to idols and special observances of days. I have freedom, Paul says, to eat meat or not eat meat, to observe a day “unto the Lord” or not. It’s not the action that pleases God, but the attitude of the heart. Are you doing it out of obedience to your conscience or out of disobedience? Are you doing it with a grateful heart? If you do it but aren’t thankful, what good is it?
Bottom line: don’t judge someone else’s religious activities (assuming they are believers) and don’t put an obstacle or stumbling block in another person’s way. Verse 14 says food offered to idols in and of itself is not unclean. But if in your heart you believe it’s unclean, then to you it is. Don’t do it!
