Matthew Poole and continuators on 1 John 4:12

12 No man hath seen God at any time: If we love one another, God dwelleth in us, and his love is perfected in us.

The Essence of God is to our Eyes invisible, incomprehensible to our Minds.

But by yielding our selves to the Power of his Love, so as to be transform'd by it, and habituated to the Exercise of mutual Love, we come to know him by the most pleasant and most apprehensible Effects, experiencing his indwelling, vital, operative Presence and Influences, whereby he is daily perfecting this his own Likeness and Image in us. This is the most desirable way of knowing God, when tho we cannot behold him at a distance, we may feelingly apprehend him nigh us, and in us.
