Beacon
That you may show yourselves to be blameless and guiltless, innocent and uncontaminated, children of God without blemish (faultless, unrebukable) in the midst of a crooked and wicked generation [spiritually perverted and perverse], among whom you are seen as bright lights (stars or beacons shining out clearly) in the [dark] world,
Philippians 2:15 AMP
Those who teach righteousness will show as stars in the heavens for all of time. Surely, even as Jesus said that the one who breaks the least command and teaches others to as well shall be the least in the kingdom, righteousness and justice truly are the foundation of His throne.
He is the Father of lights, and His children are children of light. As we walk in the light as He Is in the light, we have fellowship one with another.
