Just as a spectrometer reveals the true nature of a substance under light, God’s Word tests His servants through their fruit, endurance, and obedience. Revelation 7 and Colossians 3 show that those sealed with Christ are called to put off the old self and put on a new identity marked by compassion, kindness, humility, meekness, patience, forgiveness, and love. Living as Christ’s servant requires intentional, consistent effort, allowing His Word to dwell richly and His peace to guide every decision and action.
