Meaning of "filling up in flesh"?
What does "filling up in my flesh" mean for our spiritual growth?

The Phrase in Context

“Now I rejoice in my sufferings for you, and I fill up in my flesh what is lacking in the afflictions of Christ, for the sake of His body, which is the church.” (Colossians 1:24)


Paul’s Joyful Suffering as a Pattern

• Paul is physically suffering while imprisoned, yet he “rejoices.”

• His trials are not random; they benefit “the church.”

• He models an outlook that treats hardship as intentional participation in Christ’s ongoing work.


“Filling Up” – What It Is Not

• Not adding merit to Christ’s atoning sacrifice—His cross is perfectly sufficient (John 19:30; Hebrews 10:14).

• Not suggesting Christ failed to suffer enough; the context concerns ministry, not redemption.


“Filling Up” – What It Is

• Completing the share of suffering appointed to Christ’s servants as they spread the gospel (Acts 9:16).

• Displaying, in visible human bodies, the same sacrificial love that Christ displayed in His (2 Corinthians 4:10–11).

• Advancing the church by absorbing hostility that would otherwise be aimed directly at new believers (Ephesians 3:13).


Spiritual Growth Benefits

1. Deepened Union with Christ

• “That I may know Him…and the fellowship of His sufferings.” (Philippians 3:10)

2. Purified Character

• Endurance produces proven character and hope. (Romans 5:3-5)

3. Enlarged Love for the Church

• Bearing hardship “for you” cements affection for fellow saints (2 Timothy 2:10).

• We value the body more when we pay a price to serve it.

4. Eternal Reward

• “If we endure, we will also reign with Him.” (2 Timothy 2:12)

• Current afflictions prepare “an eternal weight of glory.” (2 Corinthians 4:17)


Practical Steps to Embrace Christ’s Afflictions

• Respond to personal trials with gratitude, viewing them as participation in Christ’s mission.
