The Epistles of John, assigned to the writer of the Fourth Gospel and the Revelation, testify that God is love and that love is the test of religion. Second John is written to “the elect lady and her children,” probably a church; Third John is addressed to “the beloved Gaius.”

1 John 3

3:22 And whatsoever we ask, we receive of him, because we keep his commandments, and do those things that are pleasing in his sight.
