There are those who have so closely identified themselves with the truth that nothing, not even martyrdom and death, could sever them from it. Those who would evade the truth by silence, fearing to offend someone else, testify to a lie. Playing fast and loose with truth and dissembling to suit the opinions of someone else, means the shipwreck of faith. Let us despise falsifying. Let us never by a word or act or by silence testify to a lie....
All who make untruthful statements ... are serving him who has been a liar from the beginning. Let us be on our guard against untruthfulness, which grows upon him who practices it. I say to all, make truth your girdle. Be true to your faith. Put away all prevarication and exaggeration. Never make a false statement. For the sake of your own soul and the souls of others, be true in your utterances. Never speak or act a falsehood. The truth alone will bear to be repeated. A firm adherence to truth is essential to the formation of Christian character. “Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness” (Ephesians 6:14).
He who utters untruths sells his soul in a cheap market. His falsehoods may seem to serve in emergencies. He may make business advancement because he gains by falsehood what he could not gain by fair dealing. But he finally reaches the place where he can trust no one. Himself a falsifier, he has no confidence in the word of others.
There is absolutely no safeguard against evil but truth. No man can stand firm for right in whose heart the truth does not abide. There is only one power that can make and keep us steadfast—the power of God, imparted to us through the grace of Christ.
Connected with Christ, human nature becomes true and pure. Christ supplies the efficiency, and man becomes a power for good.... Truthfulness and integrity are attributes of God, and he who possesses these qualities possesses a power that is invincible. HP 179
All who really desire it can find a place for communion with God, where no ear can hear but the one open to the cries of the helpless, distressed, and needy—the One who notices even the fall of the little sparrow. He says, “Ye are of more value than many sparrows.” (Matthew 10:31) Pr 212
"The lip of truth shall be established for ever: but a lying tongue is but for a moment." Proverbs 12:19 (King James Version)
