How Do You Know If You Are a Liar?

How Do You Know If You Are a Liar? (Biblical Perspective)

The Bible provides clear teaching on what it means to be a liar, the consequences of lying, and how to examine yourself honestly. Here’s how you can determine if you are living as a liar according to Scripture:

1. A Liar is Someone Who Speaks Falsehood as a Pattern of Life

Proverbs 6:16-19 – “There are six things that the Lord hates, seven that are an abomination to Him: haughty eyes, a lying tongue, and hands that shed innocent blood…”
Psalm 58:3 – “The wicked are estranged from the womb; they go astray from birth, speaking lies.”
If lying is a regular habit—whether for personal gain, avoidance of consequences, or deception of others—you are living as a liar.

2. A Liar is Someone Who Practices Deceit

Jeremiah 9:5 – “Everyone deceives his neighbor, and no one speaks the truth; they have taught their tongue to speak lies; they weary themselves committing iniquity.”
Lying is not just about speaking outright falsehoods, but also about being deceptive—manipulating, withholding truth, or twisting words to mislead others.
Ask yourself: Do I deceive others, even in small ways?

3. A Liar is Someone Who Justifies Their Lies

Isaiah 5:20 – “Woe to those who call evil good and good evil, who put darkness for light and light for darkness.”
If you find yourself rationalizing dishonesty—thinking “It’s not a big deal” or “Everyone does it”, you may be falling into a pattern of lying.
Proverbs 21:2 – “Every way of a man is right in his own eyes, but the Lord weighs the heart.”
Ask yourself: Do I excuse my lies instead of repenting?

4. A Liar is Someone Who Pretends to Follow God but Lives in Falsehood

1 John 1:6 – “If we say we have fellowship with Him while we walk in darkness, we lie and do not practice the truth.”
1 John 2:4 – “Whoever says ‘I know Him’ but does not keep His commandments is a liar, and the truth is not in him.”
Living a double life—professing faith while practicing deception—is a serious warning sign.
Ask yourself: Do I claim to follow God but live in dishonesty?

5. A Liar is Someone Who Imitates Satan, the Father of Lies

John 8:44 – “You are of your father the devil, and your will is to do your father’s desires. He was a murderer from the beginning and does not stand in the truth, because there is no truth in him. When he lies, he speaks out of his own character, for he is a liar and the father of lies.”
Satan’s very nature is deception—he distorts truth, tempts people to lie, and seeks to destroy through falsehood.
Ask yourself: Am I following the example of Christ, who is truth (John 14:6), or am I imitating Satan’s ways?

6. A Liar is Someone Who Refuses to Repent

Revelation 21:8 – “But as for the cowardly, the faithless, the detestable, as for murderers, the sexually immoral, sorcerers, idolaters, and all liars, their portion will be in the lake that burns with fire and sulfur, which is the second death.”
Persistent, unrepentant lying has eternal consequences.
Ask yourself: When I recognize dishonesty in myself, do I confess it and seek change, or do I continue in it?

The Way Out: Repentance and Walking in Truth

If you recognize lying in your life, the good news is God offers forgiveness and transformation:

Proverbs 28:13 – “Whoever conceals his transgressions will not prosper, but he who confesses and forsakes them will obtain mercy.”
1 John 1:9 – “If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness.”
Ephesians 4:25 – “Therefore, having put away falsehood, let each one of you speak the truth with his neighbor, for we are members one of another.”

A liar can become a truthful person by repenting, seeking God’s help, and committing to a life of integrity.

Final Question: Are You Willing to Walk in Truth?

If this convicts you, don’t ignore it. God is calling you to truth. Are you willing to confess any deception in your life and commit to speaking and living truthfully?
