“Let your light so shine before men, that they may see your good works and glorify your Father in heaven.”—Matthew 5:16 JNN 219.1
Paul writes, “Do all things without murmurings and disputings that ye may be blameless and harmless, the sons of God, without rebuke in the midst of a crooked and perverse generation, among whom ye shine as lights in the world; holding forth the word of life, that I may rejoice in the day of Christ that I have not run in vain neither labored in vain” (Philippians 2:14-16).... JNN 219.2
How much do persons who are not themselves under God’s control, although professing to be Christians, really contribute to the efficiency of the gospel in their business relations with those who are not converted? There are many against whose names on the record books of heaven will be found written, Not producers, but consumers. They do not bear fruit to the glory of God. The Lord cannot co-operate with them. They are stones which take up room in the building, but emit no light. They cannot shine as living stones, because they do not receive light from the chief Cornerstone. Can they afford to trust their souls any longer to such uncertainty? Christians are either under Christ’s rule, heeding His instruction by doing the work they are supposed as God’s followers to be doing, or they are under the control of the enemy. They are either doing positive good or incalculable harm.... JNN 219.3
Christians are to be light-bearers, saying to all with whom they are brought into contact, Follow me as I follow Christ. They are to be examples of piety, representing Christ in word, in spirit, in action, in all business dealing with their brethren and with strangers. They are to show that their actions are a copy of the actions of their great Pattern. All this Christ enjoins upon His followers. They are to show the superiority of heaven’s principles over the principles of the world.... JNN 219.4
True Christians will always shine as lights in the world. They are light-bearers, working upon a higher plane of action than those who are not Christians. Their purity and uprightness in every action is a source of illumination. They impart what they receive, making known the duties and privileges of a Christian. The refining, ennobling principles of the gospel are brought into every phase of life.—Letter 148, 1899. JNN 219.5
Further Reflection: What “incalculable harm” might I do if I am unconsecrated to God? JNN 219.6
