Ephesians 6:14 Stand firm then, with the belt of truth buckled around your waist,
In this fight against the evil the first tool we are given is the belt of truth. Truth brings light to the world. Without understanding what is true and what is a lie will will never be able to stand against the devils tricks.
His greatest (only) weapon against us are his lies.
You belong to your father, the devil, and you want to carry out your father’s desires. He was a murderer from the beginning, not holding to the truth, for there is no truth in him. When he lies, he speaks his native language, for he is a liar and the father of lies.
Jesus told us “I am the way and the truth and the life. No one comes to the Father except through me.” John 14:6
When we seek truth first we find the way to life and the Father in heaven.
So fight with the truth that comes from the Spirit of God. His promises are always true, His grace is always there, and His love never ends.
