1 John 4:6

Verse 6. We (Christians) are of God, have received the Spirit; we, the apostles of Christ, were lawfully sent by him.—He that knoweth God, heareth us, and so forth That is, they who love and serve God, and comply with the doctrine of his Son, Jesus Christ, hear and follow the doctrine which we were commissioned by him to teach.—He that is not of God, heareth us not. They are not of God, who refuse to hear and obey the voice of the Church and those whom Christ appointed to govern his Church, as hath been observed elsewhere.—By this we know the Spirit of truth and the spirit of error. Here Saint John gives them the second general mark and rule, to preserve them and all Christians from errors and heresies to the end of the world. He that knoweth God, heareth us Apostles, whom he sent, and heareth our successors, invested with the same mission and authority, whom Christ sent, as his heavenly Father sent him, whom he appointed to govern his Church, and with whom he promised to remain to the end of the world. Witham.
