A lie led to the death of Abel by his brother Cain. A lie brought God's Son to His death. And through lies, the world, the flesh, and the devil imply that all the sin in the world is God's fault. God gave us the power of speech to communicate. It can communicate truth or lies.
Words are seemingly endless and unperishable.
There are lies from Bible characters recorded in the Word of God that will live for eternity and will never be erased. Do not think for a moment that your dishonesty goes untouched just because people have not been discerning. God knows about it. No other human being was there when Satan lied to Adam and Eve, but all of us know about it. The conflict of the ages is the conflict between the truth versus a lie.
