Which covenant are God's elect under in order for them to inherit eternal life in the world to come? Certainly not the covenant of work which Adam was he head of.
Any thoughts, before I post some scriptures proving that we are under the everlasting covenant of pure grace.
Show me the Scripture where God makes such covenant with Adam.
Where does God say, "I make a covenant with you." or words to that effect like He does with Noah and Abraham, etc.
8 And God spake unto Noah, and to his sons with him, saying,
9 And I, behold,
I establish my covenant with you, and with your seed after you; Genesis 9:8–9.
7 And
I will establish my covenant between me and thee and thy seed after thee in their generations for an everlasting covenant, to be a God unto thee, and to thy seed after thee. Genesis 17:7.
When God makes covenant, He says so. There are also terms, longetivity, and words that describe a covenant is being made.
Short of this there is no covenant.
