Answer
Any service that reflects Jesus’ love is “Christian service.” From giving a cup of water (Mark 9:41) to dying for someone (John 15:13), there are as many types of Christian service as there are needs in the world. Very few involve activity within the four walls of the church.
The Bible gives some specific examples of Christian service: show hospitality to strangers (Hebrews 13:2), remember those in prison (Matthew 25:36), provide for the needy (Matthew 25:35), and mentor others (Titus 2:2-8). Some examples speak to our day-to-day living: care for children (Matthew 18:5), tend families (Titus 2:5), treat employees fairly (Colossians 4:1), deal honestly with customers (Leviticus 19:36), and be diligent with employers’ resources (Matthew 25:14-30). As long as the act is done “in Jesus’ name”—that is, it is motivated by the love of Jesus—it is Christian service.
There are thousands of organizations outside the church committed to serving others. Homeless shelters, housing builders, and food banks always need volunteers and donations. Internationally, organizations like Compassion International provide food, clothing, and education for children in sometimes dangerous situations. Other ministries provide water, micro-loans, or resources such as farm animals to enable the child’s family to generate their own income.
The world outside the walls of the church offers many opportunities for those specifically educated in theology. Chaplains serve hospitals, military bases, and shipping ports. Foreign missionaries travel overseas to plant churches and train indigenous pastors. Parachurch ministries provide biblical guidance for families and others in need. And internet ministries like Got Questions are always in need of those who can explain the truth of God in a loving, easy-to-understand way.
The world is in desperate need of Christians willing to show the love of Christ through their actions. Jesus said the second greatest commandment was to love others—not sentimentally, but tangibly. Every action performed out of kindness, powered by the understanding of Christ and His love, is Christian service.
