Multiple levels of understanding of freedom in Christ.

• One does because he’s weak. He doesn’t understand that he’s free, but he does it anyway.
• One doesn’t because he knows he’s weak. He is beginning to understand freedom, but knows he’s not strong enough to engage in the activity.
• One does because he’s strong. He understands his freedom in Christ and knows that there is good in all things.
• One doesn’t because he’s disciplined and doesn’t need to. “All things are lawful for me, but not all things are profitable.”

etc.

The problem is that when I see another Christian act differently than me, I will usually assume that I am a level beyond him in maturity rather than a level behind. This is why there are so many conflicts over the “gray areas” in the Christian life.
