1 Corinthians 11
25 After the same manner also [he took] the cup, when he had supped, saying, This cup “is” the new “testament” in my blood: this do ye, as oft as ye drink [it], in remembrance of me.
A Testament (diathéké: Covenant, Testament) is a contract, a covenant, an agreement between two parties. The two parties to the New Covenant are God and each individual agreeing to perform, TO DO, to live by the terms and conditions i.e. “by every Word that proceedeth out of the mouth of God. “
Jesus Christ was clear, “”every Word”” The Tora, the Old T and the New T came from the mouth of God.
Within a covenant or contract there are agreed upon terms and conditions which each party has agreed to perform. A covenant is not one sided, both parties will have duties, obligations they must fulfill.
The New Covenant establishes a “Relationship” for those agreeing to the requirements and terms in the New Covenant. By The New Covenant, God the Father brings those He alone calls, into A Father/Son intimate relationship.
Each Party to a Covenant must perform the terms and conditions set forth in the covenant. A Covenant is not one sided, both parties have duties and conditions they have agreed to perform.
Under the terms of the New Covenant, God has agreed to give eternal life to all those willing to obey, to live according to God’s ONE ‘narrow’ WAY defined by His Law.
The entirety of the WORD, both Old and New, states no one will be given eternal life that has not come out of sin, repented of sin.
What defines sin and who has the right to define, codify sin?
Yes, humans must be converted, must have their sinful human nature replaced by the Divine Nature of God to gain Eternal Life!
2 Peter 1
4 Whereby are given unto us exceeding great and precious promises: that by these ye might be partakers of the divine nature, having escaped the corruption that is in the world through lust.
Contrary to accepted doctrine (grace), the New Covenant established by Jesus Christ, requires Christian’s to obey Every Word of God and be transformed, converted by God The Father’s Spirit working in them into living God’s ONE sinless perfect Way.
Our Father and His Son will not enter a family relationship with sinners. Rev 21: 8
You can ignore the words of our Maker at your own peril. 4 But he answered and said, It is written, Man shall not live by bread alone, but by every word that proceedeth out of the mouth of God.
“The Bible” came directly from the mouth of God, the whole Bible.
Jesus Christ stated clearly --- “by every Word” --- not just those you agree with.
