This sermon concludes our series in Philippians. In his concluding words, Paul shows how the Christian depends completely on God's grace for all of life: faith and practice. That is seen in his sense of church unity in v. 21-22, and in his final words to the Philippians church in v. 23. There is also a final overview of the main theme of the book and how it is implemented in each chapter.
After some significant turmoil as a result of Pharaoh's hard-hearted rebellion against God, the Lord reassures the people of Israel by appealing to the promises of the past, confirming that he hears their cries in the present, and restating that he will fulfill his promises in the future. As always, the connection from Exodus to Christ is made.
