I was struck with the simplicity of these verses and how much they sounded like a 'formula' for godly living to me (and I love formulas).
We live "in the midst of a crooked and perverse generation."
Who wants to "shine as lights in the world?" (me, raising my hand)
Who wants to be "blameless, innocent children of God without fault?" (me, raising both hands)
"Do all things without complaining and arguing." (ouch!)
: ) Blessings!
