When you went to a good restaurant recently, did you notice that the main course was carefully placed on the plate? How about a really good website? Often, when we find one that we really like, it's look is important to our assessment.
Now we draw together this reality of life and consider our witness as a regular course of who we are. Are we presentable? Oh, you say it depends upon our audience. Sure. I can see that. Now, are you presentable? The success might be found in the receptivity.
My point is that we cannot just leave our witness up to chance when God has given us the good sense to sort out the audience and make necessary adjustments. Does this make us less than authentic? I think not. It makes us effective.
"And whatsoever ye do in word or deed, do it all in the name of the Lord Jesus, giving thanks to God and the Father by Him." Colossians 3:17 KJV
