Colossians 3:23 says we should do everything as if we are doing it for God. Recently I was contemplating other reasons we do our best. I came up with this:
Excellence is all about removing distractions so people can hear the gospel of Jesus Christ.
If the only thing people notice is misspelled words, broken microphones, or dirty walls in church, they may miss the most important thing - hearing the gospel! When I am in church and see something wrong, it distracts me. I’m pretty sure it distracts other people, too.
If the only thing someone sees in you is that bad habit, your unbrushed teeth and halitosis, or the way you mistreat your wife and kids, they will likely not hear the gospel from you.
In your pursuit of excellence, always be reminded of Psalm 16:2-3:
2 I say to the LORD, “You are my Lord; I have no good apart from you.”
3 As for the saints in the land, they are the excellent ones, in whom is all my delight.
