<p>15:11- see on 1 Jn. 1:4.</p><p><em>These things have I spoken to you, that my joy may be in you, and that your joy may be made full</em>- The filling up of joy means that something will be done to us within our hearts; for that is where &quot;joy&quot; is experienced. 'Filling up' is the language of the ongoing filling of the Spirit, which is the context of this whole section in chapters 14-16. The Lord's spirit, His way of being and thinking, His mind, included &quot;joy&quot;. He wished to give His spirit to us, so that His spirit might become ours; and thereby His joy would be within us. His &quot;joy&quot; is expressed in the Gospels as joy over a lost sheep being found (Lk. 15:7), the joy of finding people for the Kingdom (Mt. 13:44), the joy of seeing others enter His Kingdom (Mt. 25:21). What He rejoices in, we shall. His joy shall be in us in that we share His spirit, His attitude and mindset (17:13). John himself experienced this when he wrote of having joy that his converts were abiding in Christ; and he could think of &quot;no greater joy&quot; (3 Jn. 4).</p>
