“We are of God: he that knoweth God heareth us; he that is not of God heareth not us. Hereby know we the spirit of truth, and the spirit of error.”
King James Version (KJV)
4:6 We - Apostles. Are of God - Immediately taught, and sent by him. Hereby we know - From what is said, #1Jo 4:2 |- 6.
1Jo 4:6 We are of God. Hence speaks God's message, and those that know God accept the message. Hereby know we the spirit of truth, and the spirit of error. By the principles given in 1Jo 4:2-5 we distinguish between the spirit of truth (the Holy Spirit) and that of error.
