"Flee also youthful lusts: but follow righteousness, faith, charity, peace, with them that call on the Lord out of a pure heart." (2 Timothy 2:22)

"I have no greater joy than to hear that my children walk in truth." (3 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 3 John, it occurs six times.

"And if the servant shall plainly say, I love my master, my wife, and my children; I will not go out free: Then his master shall bring him unto the judges; he shall also bring him to the door, or unto the door post; and his master shall bore his ear through with an aul; and he shall serve him for ever." (Exodus 21:5, 6)

"Wherefore be ye not unwise, but understanding what the will of the Lord is." (Ephesians 5:17)

"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)
