“I have no greater joy than to hear that my children walk in truth” (III John 4).

The important word “truth” is a key word in the apostle John’s vocabulary, occurring more in his writings than in those of any other New Testament author. In the one-chapter epistle of III John, it occurs six times.

“Who hath wrought and done it, calling the generations from the beginning? I the LORD, the first, and with the last; I am He” (Isaiah 41:4).

“I am Alpha and Omega, the beginning and the ending saith the Lord, which is, and which was, and which is to come, the Almighty” (Revelation 1:8).

“And He said unto him, I am the LORD that brought thee out of Ur of the Chaldees, to give thee this land to inherit it” (Genesis 15:7).

“And God said unto Moses, I AM THAT I AM: and He said, Thus shalt thou say unto the children of Israel, I AM hath sent me unto you” (Exodus 3:14).
