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 2

2:21 I have not written unto you because ye know not the truth, but because ye know it, and that no lie is of the truth.
