<p>15:21 <em>But all these things will they do to you for my name's sake, because they do not truly know Him that sent m</em>e- John later speaks about those who fulfil the great commission as going forth for His name's sake (3 Jn. 7). Throughout this section, the Lord is speaking about the need to follow the great commission and preach forgiveness and repentance in His name (Lk. 24:47). If His Spirit, His word and essence, abode in them, then they would experience the same opposition which He did. Their 'not knowing' the Father who sent the Son would be the basis of their hatred of the preachers. On the other hand, to know the Father is to have relationship with Him, and love His children. John's letters develop this same theme; to not love is to not have a relationship with the Father.</p>
