John MacArthur Study Bible
We urge you. Paul has discussed how the pastors are to serve the people and how the people are to respond to the pastors (vv. 12, 13). In these verses, he presents how the people are to treat each other in the fellowship of the church. The “unruly,” those out of line, must be warned and taught to get back in line. The “fainthearted,” those in fear and doubt, must be encouraged and made bold. The “weak,” those without spiritual and moral strength, must be held up firmly. Patience, forgiveness, and acts of goodness must prevail among all the people. † 5:16–22 Paul gave a summary of the Christian’s virtues. These verses provide the foundational principles for a sound spiritual life in brief, staccato statements that, in spite of their brevity, give believers the priorities for successful Christian living.
