God Is Trustworthy: Resting In The Assurance That God Cannot Lie

The Bible teaches us that God is the truth and cannot lie[1]. This fundamental belief is expressed in several passages throughout Scripture, such as Titus 1:2 which states, “In hope of eternal life, which God, who cannot lie, promised before the world began.”

In Hebrews 6:18, we read that “God… cannot lie.” What does this mean for us as believers in God? It means that we have a source of absolute truth and trustworthiness. We can be sure that when God promises something, He will keep His word.

What Does “God Cannot Lie” Mean?

This is a Biblical truth that has its foundation in God’s very nature and character. According to Titus 1:2, God’s promises are true because He cannot lie. His Word is reliable and trustworthy, and His righteous rules endure forever.

The Bible is filled with verses affirming this statement. Therefore, His promises are certain: “For no matter how many promises God has made, they are “Yes” in Christ” (2 Corinthians 1:20). This verse signifies that God’s promises are true and dependable because of two unchangeable things—He cannot change His mind or break His promises.

The Bible also reveals that God is perfect in all of His ways—He does not “change like shifting shadows” (James 1:17). This means that He is consistent and can never speak or act contrary to His character; He cannot go against what He said, nor can he make a false promise.

In addition to being a reliable source of truth and promise-keeping, God’s inability to lie has an even greater significance. Because He cannot lie, He is the ultimate source of truth—any truth that comes from Him can be believed without doubt. This means that anything He has said in His Word is true and trustworthy; therefore, it can form the foundation for our beliefs and values.

God’s immutability also means that His promises are timeless—they will never change or expire because He Himself cannot change or expire. This security gives us hope set during difficult times because we know that God does act faithfully on His promises and will never fail us.

Ultimately, God’s inability to lie reminds us of His perfect character and presence in our lives. We can take comfort in knowing that we have a dependable God who is faithful to His promises and can never go back on them. He is the ultimate source of truth and love, and His Word stands firm forever. Because of this, we can put our trust fully in Him and rely on Him for all things.

7 Reasons Why God Cannot Lie

Both God and Jesus Christ—as the utmost embodiment of truth, grace, and integrity—cannot lie. This concept has been accepted by millions worldwide as one of His fundamental attributes. Here are 7 reasons why God cannot lie:

1. God’s Perfect Nature

As the supreme being, God is perfect in every way, and His perfection does not allow for lies. He is honest and truthful in all He does and doesn’t need to lie to achieve His will. By nature, He cannot be deceitful or untruthful; any attempt at lying would detract from His perfection.

God’s perfect and unchanging nature is also reflected in His divine justice. He is always fair and just in all His judgments, never allowing for prejudice or favoritism. Instead, God looks at the heart of each individual and treats them accordingly. This justice allows Him to love people equally regardless of race, gender, social standing, or another characteristic.

2. God’s Hatred Of Sin

Lying is a form of sin and as such, it goes against the very nature of God. He abhors anything that distorts the truth or causes harm to others; by disallowing himself from lying, He has also set an example for us to follow!

The Bible makes it clear that God hates all forms of sin. In Habakkuk 1:13, God speaks by expressing His disdain towards all the wickedness and injustice prevalent in the world, stating that “your eyes are too pure to look on evil; you cannot tolerate wrong.” For this reason, God will not tolerate any form of sin and will punish transgressors for their actions.

3. God’s Word

When God speaks, it is done with authority, honesty and certainty. He has revealed Himself to us in His written word (the Bible) and we can trust that what is recorded there is true and accurate. Any attempt of Him to lie would decrease its reliability as our source of truth!

4. Divine Justice

As the ultimate judge, God knows all things—past, present, and future—making it impossible for Him to lie or be deceived by anyone. This ensures justice is served accurately at all times; no one has the power to manipulate God to bear false witness or engage in trickery!

5. God’s Promise

Throughout history, God has made many promises, some of which are so important that they have been recorded in the Bible. He is faithful to fulfill His promises, even when we are not; lying would go against His integrity and reliability as a perfect provider.

6. God’s Plan

God has an ultimate plan for us, and nothing He does or says will ever get in the way of this. Every word He speaks aligns with His greater purpose for us and because of this, any untruthful statements would be counter-productive to everything else He desires to accomplish.

7. God’s Spirit

For us to know and experience the truth about God, we need the help of the Holy Spirit. As our guide, no falsehood can be found within the Spirit, as God’s very essence is truth itself.

Why Is It Important To Understand That God Cannot Lie?

Understanding this statement is of great importance for various reasons. Firstly, it gives us confidence in the reliability and trustworthiness of God’s promises. If God is incapable of lying, then we can be assured that everything He says is true and will come to pass. This is especially important regarding our salvation, where we rely on God’s promises of forgiveness and eternal life.

Secondly, it helps us to discern truth from falsehood. We live in a world where lies and deception are prevalent, and it can be challenging to discern what is true and what is not. However, if we understand that God cannot lie, we can use this as a standard to measure the truthfulness of other claims. If something contradicts what God has revealed in His Word, then we know it cannot be true.

Thirdly, it gives us assurance that His character is unchanging. The Bible tells us that God is the same yesterday, today, and forever, and that He does not change like shifting shadows. This means that we can always trust in God’s goodness, love, and faithfulness, even amid difficult circumstances.

Lastly, it helps us to avoid the temptation to doubt or question God’s goodness. When we face trials and hardships, it can be easy to question God’s intentions or think He is not acting in our best interest. However, if we have a firm conviction and faith that God cannot lie, we can trust that He is working all things together for our good, even if we don’t understand it now.

In the end, God cannot lie. This is based on the teachings of both Old and New Testament scriptures. The Bible shows us how trustworthy He is and His promises to never break a covenant with His people are repeatedly fulfilled.

As Christians, we know that our Heavenly Father will never deceive or mislead us. Though He may use circumstances and lessons to bring us closer to Him, we can be certain that God will always remain true to His Word as His righteous rules endure forever. He is a faithful God who never fails, and His promise of eternal life is our ultimate assurance of this truth.
