1 John 3:11

For this is the message
Sent from God by Christ, or what he in his ministry declared, and is the commandment which was so frequently urged by him, ( John 13:34 ) ( John 15:12 John 15:17 ) ;

that ye have heard from the beginning;
of the preaching of the Gospel to them, and of their conversion; see ( 1 John 2:7 ) ;

that we should love one another;
to which the command of Christ, the reason with which it is enforced, and the early notice of it, should engage.
