Since God is “a God of truth” (Deuteronomy 32:4), it makes sense that the words proceeding forth from His mouth would reflect and demonstrate the same nature as their author. According to the scriptures, this is exactly what has happened. The psalmist said, “thy law is the truth” (Psalm 119:142) “and all thy commandments are truth” (Psalm 119:151). The Lord Jesus confirmed this when He said, “Sanctify them through thy truth: thy word is truth” (John 17:17). If God is worthy of praise for being a God of truth, it only makes sense that His truth would also be worthy of man’s praise (Psalm 71:22). God, knowing this truth, magnified His word above all His name (Psalm 138:2).
The context of our passage is the sinfulness of God’s people, particularly those residing within the city of Jerusalem. The city is said to have “wearied herself with lies.” A similar truth is taught in Jeremiah 9:5 where the Bible says, “they have taught their tongue to speak lies, and weary themselves to commit iniquity.” The context is different, but the concept remains constant: it requires hard work to tell and sustain lies. Anybody that has ever told a lie knows that it takes much greater effort to sustain a lie than to simply let the truth stand upon its own merit. Among other things, lying takes creativity, calculation, and a good memory. Additionally, lying stresses a person’s conscience. Very rarely does one lie suffice within any particular deception, but the original lie often requires additional lies to support it. Lying is hard work and very stressful for those who have not seared their conscience!
The Devil was created perfect in every aspect (Ezekiel 28:15) with complete capacity to do right. Yet, he was also created with a free will to choose whether to do right or to do wrong. Sometime in the distant past, he chose to abide “not in the truth.” This conscious decision to depart from the truth caused him to become the “father” of lies. In one form or another, every lie traces back to the work of the Devil. As the enemy of God, Satan wants to deceive God’s creation into believing a lie so that rejecting the truth and remaining condemned in darkness (2 Corinthians 4:4) seems like the natural thing to do. Satan incorporates every deceptive means at his disposal. One of his main tactics is to convince people that there are many ways to heaven (good works, baptism, church membership, etc.) and many ways to know the truth (feelings, science, circumstances, etc.). Yet, the Bible emphatically proves that God is truth and His word is truth and only through God and His word are we assured of learning and knowing truth.
The Bible describes God as a God of truth. He will not lie (1 Samuel 15:29) and cannot lie (Titus 1:2). This attribute of truth is designated to each person of the Trinity or the Godhead. Truth is declared as an attribute of God the Father in Titus 1:1-2, of God the Son in John 14:6, and of God the Spirit in John 16:13. Even the very words of God are ascribed this attribute in John 17:17 where the Bible says, “Sanctify them through thy truth: thy word is truth.” Thank God that He is truth and so is His word. A lie to the least extent within the words of God or in God’s very nature would incriminate God’s expressed deity. Lying is contrary to the nature of God. The scripture says that it is “impossible” for God to lie (Hebrews 6:18). Impossible! It would be a different world if men would simply live more like Christ.
