He who has began a good work in you will complete it.

Summary

The main theme is God's faithfulness to complete the good work He started in believers, even through setbacks. Scripture suggests that even challenging experiences, like prison, can be used by God for His purposes, exemplified by Paul's ministry. The practical takeaway is to trust God, who works all things, good or bad, for the formation of Christ in and through us, a promise for all believers.
