1 John 1:5

It being the professed scope and design of his writing, to draw men to a final participation and communion with God in his own blessedness, he reckons nothing more necessary to it, than to settle in their minds a right notion of God. Which, that it might be the more regarded, he introduces with a solemn preface; This then is the message, & c., (though the word also signifies promise, it here more fitly bears this rendering), to notify:

1. That this which follows was not an imagination of his own concerning God, but his true representation of himself.

2. That it was given him in charge to be delivered and communicated to others; a message a man neither hath of himself, nor is to reserve to himself, we have heard it of him, and declare it to you, as (consonantly hereto) he speaks. It is the Divine pleasure it should be published to the world, and that all men should know that as from him, i.e. that he is not a Being of mere power, as some, or of mere mercy, as others, are apt to fancy of him, either whereof were a very maimed and most disagreeable notion of the Deity: power without goodness were apt to run into fury; goodness without wisdom and righteousness would as naturally turn to a supine indifferency, and neglect of distinguishing judicially between good and bad; things neither suitable to the Governor of the world, nor possible to the absolutely perfect Being. God is light; in God all true perfections and excellencies must be understood eminently to concur; and of them more could not have been comprehended under one word, (especially that belong to him considered relatively to his creatures, of which perfections it concerns us to have more distinct, formed, positive conceptions in all our applications to him), than are here some way represented or resembled by light, viz. that he is a Being of most lively, penetrative vigour, absolute simplicity, immutability, knowledge, wisdom, sincerity, righteousness, serenity, benignity, joy, and felicity, and especially of most bright and glorious holiness and purity; and in whom is no darkness at all, nothing contrary or repugnant hereto.
