The indestructible Union of Jesus Christ and His Church !
The whole of Mans Salvation is wrapped up in this blessed Truth, the truth of Christ having ever died for sins is associated with this Truth, for if there was not any in union with Him when He died on the cross, then for no ones sins did He die for..
The permanent, binding and eternal union of Christ and His church, and the distinction between Adam and Christ, should be considered more here. There were two different Families in Adam and in Christ, now I believe the people are the same in each, but two different lives originate from them. The First is Natural, the Second is Spiritual. Jesus Christ existed before Adam, but Adam was the First in Manifestation in time..
Like John the baptist who from a time perspective, was manifested by physical birth before Jesus Christ, for He was six months older than He ..but John acknowledges that the man Jesus Christ existed before Him, lets read here:
Jn 1:30
This is he of whom I said, After
me cometh
a man which is preferred
before me: for he was
before me.
Notice, the Man which was preferred before Him,
and was before Him..
So Adam was the head and progenitor of all the natural Family of the elect of God; For He was earthy or of the earth, and likewise Jesus Christ [ who was before Adam] was constituted the Head and Progenitor of a Spiritual Family for He was heavenly and Spiritual.
That He existed in the beginning before all things as the Head of the Church is taught here by Paul..
Col 1:15-18
15Who is the image of the invisible God, the firstborn of every creature:
16For by him were all things created, that are in heaven, and that are in earth, visible and invisible, whether they be thrones, or dominions, or principalities, or powers: all things were created by him, and for him:
17And he is before all things, and by him all things consist.
18And he is the head of the body, the church: who is the beginning, the firstborn from the dead;
that in all things he might have the preeminence.
Christ must have the preeminence of being a Head, not Adam ! In fact, Adam was made a Head of a Family because he was made in the Image of Christ, the Heavenly God Man Mediator !
A Family must always exist in their Father or Progenitor before or prior to their development or manifestation, so it is with each head of the elect, both Adam and Christ.
