The Truth is Free
The truth is free, therefore we are free only in the truth. John 8:31&32, Then Jesus said to those Jews who believed Him, "If you abide in My word, you are My disciples indeed. And you shall know the truth, and the truth shall make you free."
Lies are always presented as truth, many times along side the truth, in order to bring us into bondage. Matt 4:5-7, Then the devil took him up into the Holy City, and set him on a pinnacle of the temple, And said unto him, If you are the Son of God, cast yourself down: for it is written, He shall give his angels charge concerning you; and in their hands they shall bear you up, unless at any time you should dash your foot against a stone. Jesus said unto him, It is written again, You shall not tempt the Lord your God.
Liars will say these same things as they present their lies as truth.
The answer: The Word of God is the Truth. John 17:17, Jesus said to His Father: Sanctify them by Your Truth. Your Word is Truth.
