We all know how we became children of our earthly fathers. We have a birth certificate. The Apostle John reminds us how we became children of our heavenly Father. It was through the blood of the Father’s Son, Jesus Christ, our Savior. We have a baptismal certificate. John, known as the “Apostle of love,” also reminds us that as God’s children, we live a life that shows love for God and love for each other.
