Why did Jesus Christ hide His Divinity from the devil?
ST. Paul the apostle says….. for had they known it, they would not have crucified the Lord of glory.
If the devil made sure that Jesus was God in presence he would never dare to cross him.
Because He said to Mousa the prophet when he wanted to see His full glory "Thou canst not see my face: for there shall no man see me, and live. "that's why Jesus Christ take the human nature to hide his glory when he was personified as man. The devil was confused to understand the personification beginning from God the word's leave to himself to take the shape of a slave and passing through all what Jesus Christ show of modesty from His birth to His escape to Egypt and His simple life which was a way from appearances of greatness, His fast on the mountain, His sadness, His prayers and to relate to himself the unknown about the last day. According to His human nature though He knows every thing.
According to His Divinity, the devil was confused when he felt that Jesus Christ is the Son of God.
The devil become confused again because of the great modesty especially in the case of knowledge that's why he dare and take the adventure with his foolishness to complete the conspiracy of crossing Jesus Christ and the fish swallowed the food in the hook and all its dreams finished till the heavenly intentions had done to the salvation and liberation of humanity from the power of the devil.
