Ephesians 2:2; Ephesians 3:1; Ephesians 3:14; Ephesians 5:31; Ephesians 6:12

2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
1 For this cause I Paul, the prisoner of Jesus Christ for you Gentiles,
14 For this cause I bow my knees unto the Father of our Lord Jesus Christ,
31 For this cause shall a man leave his father and mother, and shall be joined unto his wife, and they two shall be one flesh.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
