A lot of people don't know that they are making others feel bad when they say something about a certain practice/behavior (use of money or credit, liking certain clothes, wearing of makeup or jewelry/hair styles etc.) or serve something that someone does not like to eat or drink or engage in (pop music/dancing) that would seem to be disrespectful or degrading to the mind, body, spirit or soul.
And, some have a tendency to proclaim regularly that they don't do this/that or think a certain way, behave a certain way, wear certain clothes, and eat or drink certain foods/beverages including alcohol etc. They like to go on about how they never did that and that they weren't raised that way and that they come from a line of generations that never did. Whether you criticize directly or indirectly by proclaiming your righteousness; please, be mindful of Romans 14. You don't want to make a fellow Christian stumble.
And, yet how to point them in the right direction if you think that they are really in danger of losing their salvation. In a friendly manner, use the Word! Find scripture that they would benefit from. Let them discover for themselves the better path. They will likely see it and repent and move forward. The next time you see them and you see a change, you can say "Wow, I like that dress on you" or "you look so happy lately or well, maybe I should try that diet or cut back/take your advice."
Romans 14: 1-23
Accept other believers who are weak in faith, and don’t argue with
them about what they think is right or wrong. For instance, one person
believes it’s all right to eat anything. But another believer with a
sensitive conscience will eat only vegetables. Those who feel free to
eat anything must not look down on those who don’t. And those who don’t
eat certain foods must not condemn those who do, for God has accepted
them. Who are you to condemn someone else’s servants? Their own master
will judge whether they stand or fall. And with the Lord’s help, they
will stand and receive his approval.
In the same way, some think
one day is more holy than another day, while others think every day is
alike. You should each be fully convinced that whichever day you choose
is acceptable. Those who worship the Lord on a special day do it to
honor him. Those who eat any kind of food do so to honor the Lord, since
they give thanks to God before eating. And those who refuse to eat
certain foods also want to please the Lord and give thanks to God. For
we don’t live for ourselves or die for ourselves. If we live, it’s to
honor the Lord. And if we die, it’s to honor the Lord. So whether we
live or die, we belong to the Lord. Christ died and rose again for this
very purpose—to be Lord both of the living and of the dead.
why do you condemn another believer? Why do you look down on another
believer? Remember, we will all stand before the judgment seat of God.
For the Scriptures say,“As surely as I live,’ says the Lord,‘every knee will bend to me, and every tongue will confess and give praise to God."
Yes, each of us will give a personal account to God. So let’s stop
condemning each other. Decide instead to live in such a way that you
will not cause another believer to stumble and fall.
I know and
am convinced 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 believer 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 criticized for
doing something you believe is good. For the Kingdom of God is not a
matter of what we eat or drink, but of living a life of goodness and
peace and joy in the Holy Spirit. If you serve Christ with this
attitude, you will please God, and others will approve of you, too. So
then, let us aim for harmony in the church and try to build each other
Don’t tear apart the work of God over what you eat. Remember,
all foods are acceptable, but it is wrong to eat something if it makes
another person stumble. It is better not to eat meat or drink wine or do
anything else if it might cause another believer to stumble. You may
believe there’s nothing wrong with what you are doing, but keep it
between yourself and God. Blessed are those who don’t feel guilty for
doing something they have decided is right. But if you have doubts about
whether or not you should eat something, you are sinning if you go
ahead and do it. For you are not following your convictions. If you do
anything you believe is not right, you are sinning.
