What does Ephesians 3:16 mean?
Paul continues the prayer he began in verse 14 with a focus on the glory of God. He uses similar wording in Romans 9:23 regarding "the riches of his glory for vessels of mercy." God's glory is mentioned throughout Ephesians to repeatedly focus the reader back to Him (Ephesians 1:12, 14, 17; 3:21). Paul then asks God for deep, spiritual strength from God, through the Holy Spirit, for these Christians in Ephesus. Paul's emphasis on the Trinity in this section is again evident. He bows before the Father (Ephesians 3:14), mentions the Spirit here, and will mention Christ in verse 17 as part of the same prayer.The "inner being" is the spiritual part of a person. Paul mentions his "inner being" in Romans 7:22, saying he delights in the law of God in his inner being, or his mind (Romans 7:23). Paul desires for the Holy Spirit to work in the Ephesians' spiritual lives in great power, something the early believers experienced in Acts. Paul likewise experienced this throughout his ministry. This power did not come from mere emotions, but rather through humble prayer.
