The picture illustrates a FACT, that Christians belong to the LORD. Taken in context, God has given us the freedom of choice and we need to respect the choice of others because they have chosen Jesus.
The passage says...
Romans, Chapter 14, (World English Bible)
1 Now accept one who is weak in faith, but not for disputes over opinions. 2 One man has faith to eat all things, but he who is weak eats only vegetables. 3 Don’t let him who eats despise him who doesn’t eat. Don’t let him who doesn’t eat judge him who eats, for God has accepted him. 4 Who are you who judge another’s servant? To his own lord he stands or falls. Yes, he will be made to stand, for God has power to make him stand.
5 One man esteems one day as more important. Another esteems every day alike. Let each man be fully assured in his own mind. 6 He who observes the day, observes it to the Lord; and he who does not observe the day, to the Lord he does not observe it. He who eats, eats to the Lord, for he gives God thanks. He who doesn’t eat, to the Lord he doesn’t eat, and gives God thanks. 7 For none of us lives to himself, and none dies to himself. 8 For if we live, we live to the Lord. Or if we die, we die to the Lord. If therefore we live or die, we are the Lord’s. 9 For to this end Christ died, rose, and lived again, that he might be Lord of both the dead and the living.
In matters of choice, choose wisely and respect the choices of others because they have chosen to follow God's Christ just as you have. And, remember, as long as you have a beating heart- love your brethren!!
