Jesus said He is the Word, the Truth and the Way.
In His Word, in Eph. 6, we are taught to put on the full armour of God to fight off the powers of darkness....which would include earthly and spiritual powers. Jesus has told us and provided us with Salvation, Truth, the Word, His Righteousness, and Faith and Peace of the Gospel ....ALL of which are GREATER than the powers of evil, to overcome the temptations and lies, and false teachings of the LIAR..Satan and all of his followers.
We are warned, and taught, and encouraged to STAND IN OUR FAITH, and not be afraid, for He is with us, and will strengthen us where we are weak. He has put His own Spirit in us whose power is mighty in its greatness over all of Satan's powers.
