To have genuine fellowship with the holy God, we must walk in the light, as He Himself is in the light. It’s easy to claim to have fellowship with Him, but to be mistaken or deceived. The false teachers were claiming to have fellowship with God, but their claims were patently false. There was in John’s day, as there is today, the peril of profession, the danger of claiming to know God, but of being deceived. 1 John 2:18-27 John’s message is:
To have fellowship with the holy God, we must not walk in the darkness, but walk in the light. John 10:27-28
