We have reached the end of our series in Ephesians! This coincides with Paul reaching the end of his exhortations to the church in Ephesus (see the word, ‘finally,’ in v. 10). Drawing from the imagery of Isaiah (who depicts the Messiah as a divine warrior clothed in armor; see Isaiah 11, 52, and 59), Paul now calls Christians to use this armor in order to be ready to stand firm (verb used 4 times in this passage), especially in light of the spiritual warfare that surrounds them, and to be devoted to prayer. The sermon this week will seek to renew an awareness of the reality of spiritual warfare; call believers to stand firm in the Lord’s strength; and to be active in advancing the good news of the gospel to those who are apart from Christ.
