Those who eat must not look down on the ones who don't, and the ones who don't eat must not judge the ones who do, because God has accepted them.
Who are you to judge someone else's servants? They stand or fall before their own Lord (and they will stand, because the Lord has the power to make them stand).
One person considers some days to be more sacred than others, while another person considers all days to be the same. Each person must have their own convictions.
Someone who thinks that a day is sacred, thinks that way for the Lord. Those who eat, eat for the Lord, because they thank God. And those who don't eat, don't eat for the Lord, and they thank the Lord too.
We don't live for ourselves and we don't die for ourselves.
If we live, we live for the Lord, and if we die, we die for the Lord. Therefore, whether we live or die, we belong to God.
This is why Christ died and lived: so that he might be Lord of both the dead and the living.
But why do you judge your brother or sister? Or why do you look down on your brother or sister? We all will stand in front of the judgment seat of God.
Because it is written, As I live, says the Lord, every knee will bow to me, and every tongue will give praise to God.
References for Romans 14:11
So then, each of us will give an account of ourselves to God.
So stop judging each other. Instead, this is what you should decide: never put a stumbling block or obstacle in the way of your brother or sister.
