Romans 15:1 "We then that are strong ought to bear the infirmities of the weak, and not to please ourselves." Based on Romans 15:1, the Bible says there are strong Christians, and there are weak Christians. This can be interrupted to have something to do with eating and holiday convictions in the Romans church. My question here is "How do we define who is a weak Christian and who is a strong Christian today? Please consider the following questions and explain your answer. 1. Can a Christian who has a through knowledge of the Bible/good doctrine be a weak Christian? 2. Can a Christian who has little knowledge of the Bible/good doctrine be a strong Christian? 3. Can a Christian who is very active in the church (such as being a good minister, deacon, and teacher) be a weak Christian? 4. Can a Christian who faithfully attends church, but is not active in church activites, be a strong Christian? What do you think?
