For God is not unrighteous to forget your work and labor of love, which ye have showed toward His name.
What was this service that God would not forget? Ministering to (or caring for) the saints. Yes, God places high marks on service to other Christians. We sometimes think that service involves working for those in the world who need our help. But saints need help and encouragement too. There are many young people who are hurting and lonely and don’t know what to do or where to turn. You can help them. You can be a friend to them. You can listen to their hurts and pray with them. A true child of God will appreciate someone praying with and for them. Serve God today by serving the saints.
