11 Finally, brethren, farewell. Become complete. Be of good comfort, be of one mind, live in peace; and the God of love and peace will be with you.
Verses 11-14 comprise the greetings and benediction of Second Corinthians. Verse 11 is a series of four commands. Paul brings his correspondence with the Corinthians to a close with these verses.
11 Finally, brethren, farewell [good-bye].
Paul now begins to finish his writing of Second Corinthians. The apostle expresses the conclusion of this epistle with “farewell.” He wishes them well as brothers in Christ.
The following four commands are an appeal for unity. They are his aspirations for the church.
Become complete [restored].
The idea here is to mend your ways, make an adjustment to your problems at Corinth with integrity. The idea is to put things in order in the church so that they become a mature church. They had much to correct and construct in their church. Correction in the church was not an event but a process. Deep differences take time to resolve.
Be of good comfort,
The thought is “be exhorted.” The Greek word carries two meanings: comfort or encourage. The church needs to take Paul’s exhortation seriously. His counsel and correction will give them “comfort.”
be of one mind,
This phrase is a challenge to have a proper attitude toward one another based on shared values. This is not a challenge for a superficial truce but to have shared conformity with God’s revelation of Himself (Ro 15:4-6; Php 1:27; 2:2; 4:2). There is a need for the church to be united in unison with unbroken communion.
live in peace;
“Peace” conveys the idea of harmony (Ro 12:18; 1 Th 5:13). The Corinthians needed to live in unity with one another and forsake their divisions. There is no place for factions, slander, and jealousy in a church.
and the God of love and peace will be with you.
This phrase is a blessing from Paul. Since God is a God of love and peace, so should the Corinthians.
Christians in communion add strength to the congregation.
The Corinthian church reacted positively to Second Corinthians. We know this because Paul shaped the expansion of his ministry from Corinth on their positive resolution to their problems (2 Co 10:15-16). He wrote Romans from Corinth during his stay on the third visit (Ro 15:23).
Embers in a fire die quickly if separated. If close together, they jointly preserve the heat. Christians in communion add strength to the congregation. The fire of the ember that goes on its own will quickly lose its heat.
