Children Of God Through Faith In Christ Jesus
Those who are led by the Spirit of God are adopted in as sons and daughters of God. We are not automatically called His children at birth.
Matthew 5:9,43-48 (KJV) 9 Blessed are the peacemakers: for they shall be called the children of God. 43 Ye have heard that it hath been said, Thou shalt love thy neighbour, and hate thine enemy.
