Telling the Truth
Christians are not supported to lie, it said, “do not lie” in (Col 3:9). There was several time mentioned about “do not lie” in the Christian ethics. Other word, Christian should speak the truth and do the truth. The truth is part of freedom similar to the truth is part of righteousness.
Truth is interrelated with righteousness. In Isaiah 45:23, “Righteousness” (hq")d'c.) is the truth. Motyer said, “in all integrity is in righteousness.” “Since no preposition is expressed in the Hebrew, here, righteousness could be the subject of the sentence, in apposition to word. It would then mean an absolute truth (verse 19). It is probably best, however, to take the noun adverbially as a word invested with all the Lord’s righteous character.”51
According to E. G. White, “the truth is the word of God, faith and righteousness, and the hope of salvation, must be the armor of the successful warrior,
and his eyes must be anointed to be keen and sensitive to detect the devices of the enemy.”52
Moreover, in Isaiah 45:19, “Righteousness” (qd,c,) as “the Lord, the Lord’s word is not shifting sand but solid ground.” “He speaks truth/righteousness and what is right/plain/straightforward things.”53 God wants the truth and He speaks the truth. Similarly, the Christian believer should speak the truth.
