DEUTERONOMY 11 : 18

“Put these words of Mine in your hearts and minds; tie them as symbols on your hands and bind them on your foreheads.”
The forehead and the right hand of a person reflect his thoughts, destiny, and power. God desires mankind to let these and our whole beings be governed by His Word.
The devil also wants to control our thoughts and lives for evil by his mark. We are given the ‘sword of the Spirit,’ the Word, to defend and defeat him and his plans.
Who we follow now decides our life here and till eternity!
