I’ve Run the Race (2 Timothy 4:6-8)

The Apostle Paul is writing to assure his friend that ministry includes suffering, but also glory. This is very much an extension of Christ's life, death, resurrection, and ascension. Does this mean that we complete the work of Christ as we live out of gratitude? How should we understand the power in which we run the Christian race? Is that power our will or the Lord's power?
