10 so that you may approve the things that are excellent, in order to be sincere and blameless until the day of Christ; 11 having been filled with the fruit of righteousness which comes through Jesus Christ, to the glory and praise of God (Philippians 1).
The word “sincere” comes from a word meaning “to be found pure” — and to be found so, specifically“when unfolded and examined by the sun’s light.” In Paul’s day there was no brighter light than the sun. If you wanted to get a really good look at something, you took it outside, or at least by an opening in a wall or into a doorway so that the light of the sun would shine on it. The word “blameless” means “not causing to stumble” and was often even used to refer to “a smooth road.” Thus, both of these descriptions inherently drew the thoughts of his readers to the outside — to being outside and among others.
In other words, “sincere and blameless” hearts within always manifest themselves in a “sincere and blameless” walk without — among people. Thus, a “sincere and blameless” daily experience with Christ, as we “approve” Him and all “the things that are excellent” about Him (deeming Him worthy of adoration and service) — such a personal experience always results in a public display of holy living.
Lord, may Your light shining upon us This Day reveal only sincere and blameless hearts among us — hearts that reflect Your Light and cause no one we meet to stumble. Amen.
