This second letter of John was written to the church. It has the assurance to us that God’s Word doesn’t change. Love” is a distinguishing feature, but needs to be appropriately defined. Love is the message of God’s Word as seen in the work of Jesus for us. We also pass that love on to others. Our summary verse is from 2 John 1:5: “And now I plead with you, lady, not as though I wrote a new commandment to you, but that which we have had from the beginning: that we love one another.” – (NKJV)
