See if you understand this David.
Eph 5:30 For we are members of his body, of his flesh, and of his bones.
We are members of his body, the new man has been created.
Eph 5:31 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.
One flesh is the baby created between the union of a man and a woman.
Eph 5:32 This is a great mystery: but I speak concerning Christ and the church.
The analogy was about Christ and the believer.
Do you see it David? If we have entered into the marriage supper of the lamb then we have become married to Christ and that union has created the new man in us.
If you haven’t ALREADY done this then your lamp is not full.
