Inasmuch as non-Christians do good, they are working with Christians in doing the will of the Lord Jesus. Non-Christian goodness does not supplant or negate the lordship of Christ. It confirms and demonstrates it.
To say “Jesus is Lord” is the most political thing you can say, but not because it implies a political agenda. When we declare that Jesus is Lord and not Caesar, we are saying that the realm of life and death is not politics but the throne room of Jesus.
