<p>15:17- see on Eph. 1:5.</p><p><em>These things I command you, so that you may love one another</em>- This doesn't mean 'I command you to love one another, so that you may love one another'. The idea rather is that all the &quot;things&quot; the Lord had taught, in the word or commandment which was Him as well as in His actual words, were summarized in the need to love one another. This was and is the essence of Him, His word made flesh. See on :17.</p>
