“That you may become blameless and harmless, children of God without fault in the midst of a crooked and perverse generation, among whom you shine as lights in the world”
This religious feud whereby the Philippian church was complaining to God and to each other and arguing with each other (v.14) made a negative statement to the world. People would write them off; they would get their number; they would make allowances for them. This dispute hurt their testimony.
“that you may become blameless”
“Blameless” is the first of four standards which will contravene strife among Christians. This word means above reproach. It does not mean sinless perfection. It connotes freedom from censure. This means freedom from criticism of others.
One day we shall be spotless, faultless. That day we will be perfect and flawless:
“Now to Him who is able to keep you from stumbling, And to present you faultless before the presence of His glory with exceeding joy.” (Jude 24)
The corporate testimony of the Philippian church was at stake. They were called upon to live in such a way that those outside Christ could not rightfully point an accusing finger at them.
The church (and individuals) should take care of their image (reputation).
Before our testimony can be effective in our community, we need to set straight any broken relationships. This is especially true if we are contributing to a church at war. When non-Christians censure us, the gospel is at stake. We should give as little ground as possible for them to pick flaws in our character.
