Jesus broke down the middle wall of partition between the Jews and the Gentile, so the two could become one in Him. Your perception is determined by which side of the wall you are standing, how you see others and yourself. God framed the worlds by His Word. We must build walls around our relationship with God, around our home and families. Adam was to hedge his home with thorns to protect it from the enemy. Paul prayed for the Ephesians that their eyes of understanding being enlightened. Understanding is seeing. Understanding is the truth you stand-under. Saul was blinded by his religion until Jesus struck him with greater light and he saw he was standing under a lie. Paul outer eyes turned blind but his inner eyes opened.
