“We who are strong have an obligation to bear with the failings of the weak, and not to please ourselves” (v1). The point of being strong in faith (or in resources, or in any gift) is to “build up” others (v2). When Jewish and Gentile followers of Jesus have differences, believers should follow Christ’s example (v3) and “welcome one another,” with those who are stronger leading the way (v7). God’s plan from the beginning was for Jews and Gentiles to be one people (v8-11), united in Christ.
“May the God of endurance and encouragement grant you to live in such harmony with one another” (v5). God’s desire is that believers from different backgrounds praise Him with “one voice” (v6).
