In an open Q&A and discussion session on Sunday morning, October 14, 2018, Ken Boa teaches on Philippians 2:15–16 for a significant portion of the class. He outlines this passage using four C’s: character, culture, calling, and the coming of Christ. Followers of Christ are to have a compelling character (“blameless and innocent, children of God above reproach”), in the context of our culture (“a crooked and perverse generation”), with a clear calling (as agents of the King, we’re stewards and ambassadors; we “appear as lights in the world, holding fast the word of life,” which is timeless and powerful), as we anticipate the second coming of Christ. At the end of the teaching, he addresses a question on the issue of rewards.
… 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.
… the sons of Issachar … understood the times with knowledge of what Israel should do.
(1 Chronicles 12:32)
