A church can proclaim eternal salvation without ignoring people trapped in present injustice. Paul tells Christians in Ephesus that they were once darkness, unable and unwilling to know God, but are now light in the Lord. By God’s grace, Christ opens their eyes and changes their desires, producing goodness, right conduct and truth. God’s light does not remain passive. It exposes hidden evil, seeks others’ wellbeing through prayer and practical action, and points to Christ, whose light brings life.
