Those who have a special day for worshiping the Lord are trying to honor him. Those who eat all kinds of food do so to honor the Lord, since they give thanks to God before eating. And those who won't eat everything also want to please the Lord and give thanks to God.
For we are not our own masters when we live or when we die.
While we live, we live to please the Lord. And when we die, we go to be with the Lord. So in life and in death, we belong to the Lord.
Christ died and rose again for this very purpose, so that he might be Lord of those who are alive and of those who have died.
So why do you condemn another Christian? Why do you look down on another Christian? Remember, each of us will stand personally before the judgment seat of God.
References for Romans 14:10
For the Scriptures say, "'As surely as I live,' says the Lord, 'every knee will bow to me and every tongue will confess allegiance to God.'"
References for Romans 14:11
Yes, each of us will have to give a personal account to God.
So don't condemn each other anymore. Decide instead to live in such a way that you will not put an obstacle in another Christian's path.
I know and am perfectly sure on the authority of the Lord Jesus that no food, in and of itself, is wrong to eat. But if someone believes it is wrong, then for that person it is wrong.
And if another Christian is distressed by what you eat, you are not acting in love if you eat it. Don't let your eating ruin someone for whom Christ died.
Then you will not be condemned for doing something you know is all right.
