For what purpose did God create believers in Christ Jesus?

God created believers in Christ Jesus for good works, which He beforehand ordained that they should walk in them. As His workmanship, believers are formed to live a different life from the lost, practicing the good works God prepared for them.

Les explains that believers are God's workmanship, a work of art that God has formed. He connects the root of this word to "symphony," illustrating how many instruments come together in beautiful harmony, and says that is what God has done with us. The purpose is that we, created in Christ Jesus, should walk in good works. Because a believer is to live a different life than the lost person, we are to live and practice these good works, since God hath before ordained that we should walk in them.

Ephesians 2:10

For we are his workmanship, created in Christ Jesus unto good works, which God hath before ordained that we should walk in them.
