Charles Spurgeon Commentary 1 John 1:3-4

"that which we have seen and heard declare we unto you also, that ye also may have fellowship with us: yea, and our fellowship is with the Father, and with his Son Jesus Christ: and these things we write, that our joy may be made full." — 1 John 1:3-4 (ASV)

That which we have seen and heard declare we to you, that you also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. And these things write we to you, that your joy may be full.

Hear this, you people of God! The object of the revelation of Jesus Christ is that you may have joy—indeed, that you may have a heart full of joy and that you may know what full joy means. For, here on earth, we receive only drops and dashes of joy, unless we are brought into fellowship with God through Jesus Christ; and then, we have the very joy of God in our souls. Oh, the delight of it! Oh, that you could all know it to the full!
