Mankind was created into a covenant relationship with God. Because of the sin of Adam and Eve, the Fall, mankind is now out of relationship with God. The covenant relationship has been broken. Mankind has “fallen” from the relationship originally planned for him by God.

I agree that mankind [adam] was created in a covenantal relationship with God, but this was to serve only temporal, as Gods higher purpose for man was to have that covenantal relationship through christ and not adam, hence he purposed the Fall..You see, all things were made by [mediator] and for Jesus christ the head of the church, this was Gods eternal purpose..eph 3:

9And to make all men see what is the fellowship of the mystery, which from the beginning of the world hath been hid in God, who created all things by Jesus Christ:

10To the intent that now unto the principalities and powers in heavenly places might be known by the church the manifold wisdom of God,

11According to the eternal purpose which he purposed in Christ Jesus our Lord:

col 1:

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:

So wouldnt you agree that the creation of adam was subservient to the eternal purpose in christ ?
