In a Q&A and discussion session on Sunday morning, December 9, 2018, Ken Boa teaches on Philippians 2:15–16, with a focus on our character and calling as believers, for a significant portion of the class.

… so that you will prove yourselves to be blameless and innocent, children of God above reproach in the midst of a crooked and perverse generation, among whom you appear as lights in the world, holding fast the word of life, so that in the day of Christ I will have reason to glory because I did not run in vain nor toil in vain.
(Philippians 2:15–16)
