How many of us could drink coffee from a mug with this verse decorating its surface without feeling a pang of guilt?

Do everything without complaining and arguing,   Philippians 2:14 NLT

The world is watching.  So are fellow Believers in Christ.  When we complain we expose our faults to onlookers.

so that no one can criticize you. Live clean, innocent lives as children of God, shining like bright lights in a world full of crooked and perverse people. Philippians 2:15

Choose to be a beacon of light.
