1 Accept him whose faith is weak, without passing judgment on disputable matters. 2 One man's faith allows him to eat everything, but another man, whose faith is weak, eats only vegetables. 3 The man who eats everything must not look down on him who does not, and the man who does not eat everything must not condemn the man who does, for God has accepted him. 4 Who are you to judge someone else's servant? To his own master he stands or falls. And he will stand, for the Lord is able to make him stand.
The apostle refers to Christians who have various degrees of faith. One may have a strong enough faith to realize they are free in Christ while another depends on following strict guidelines. One may have realized there are certain rules man has made trying to please God, while the other follows man’s rules because they are too weak to determine their path. In either case one is not to judge the other for God has accepted them. Those who have accepted Christ are His and who is anyone else to challenge His authority.
What is the freedom given in Christ? It is the freedom to enjoy whatever choices we make not addressed by the scriptures. The things God commands: We should do. The things God condemns: We should stay away from. We should be able to make these choices without fear or punishment from other believers; but that is not always the case. Proverbs 16:2 says, “People may be pure in their own eyes, but the Lord examines their motives.” Again in Proverbs 21:2, “People may be right in their own eyes, but the Lord examines their heart.” These verses show sometimes people fool themselves into their own beliefs, but God knows their true intent. Even Proverbs 20:6 says, “Many will say they are loyal friends, but who can find one who is truly reliable?” Isn’t it true some who say they live as God would have them are not always reliable and loyal? So we cannot go by the criticism of others but by God’s desire. Are you listening to the desires of God? Pray God would open your heart to listen as He speaks to you. Pray you will know the right choices to make in life. Ask the Lord to keep you on a path that keeps you free from sin.
