Scripture
So why do you condemn another believer? Why do you look down on another believer? Remember we will all stand before the judgement seat of God.
Observation
We are to accept other believers and not argue with the,. Some people think that certain foods should not be eaten. Other people think that certain days should be considered more holy than others.
We should not argue with one another about these issues. What is important is that all believers do what they do to honour the Lord.
We mustn't condemn other people. After all we will stand before God's judgement seat in same way that they will.
Application
Paul is remarkably relaxed about religious observances regarding food, holy days or other practices.
His main concern is that we do what we do out of love for the God, and not in the belief that religious practices will bring salvation.
Many church splits and denominational differences would be avoided if we chose to love one another rather than judge one another.
Prayer
Father forgive me for judging brothers and sisters in Christ. Help me to love those with whom I disagree. Amen.
