Some Think the Only Difference Between the Old and New Covenant is a Blank Page

Matthew 26:26-30
26 While they were eating, Jesus took bread, gave thanks and broke it, and gave it to his disciples, saying, "Take and eat; this is my body."
27 Then he took the cup, gave thanks and offered it to them, saying, "Drink from it, all of you.
28 This is my blood of the new testament, which is poured out for many for the forgiveness of sins.
29 I tell you, I will not drink of this fruit of the vine from now on until that day when I drink it anew with you in my Father's kingdom."
30 When they had sung a hymn, they went out to the Mount of Olives.

The Greek word for "testament" used here is "DIATHEKE," and it primarily denotes a contract, covenant, agreement, or promise (Ga 3:17). Vine's Expository Dictionary of New Testament Words states that this Greek word "does not in itself contain the idea of joint obligation, it mostly signifies an obligation undertaken by a single person." In other words, in the New Covenant, it is not what we can do for God but what God has done for us.

The principle of the Old Covenant was "do" and we shall live (Ro 10:5). The principle of the New Covenant is "it is done" (Ro 10:6-9), and that includes redemption, reconciliation, righteousness, and sanctification. The work is finished! We are complete in Him (Col 2:10)!

If the Old Covenant had been without defect, there would have been no attempt to institute another (Heb 8:7). In the Old Covenant, people found themselves unable to abide in its agreement, for it was based upon people's performance (Ex 19:5-8). The new agreement, however, was based totally upon God's grace (Ro 4:4-5). Under the Old Covenant, people approached God through a priest (Heb 5:1), while under the New Covenant, people have direct access to the Father through Jesus Christ (Heb 4:16).

Under the Old Covenant, people's sins led to their deaths (Heb 10:28), while under the New Covenant, God is merciful to people's unrighteousness (Heb 8:12; 1Jo 1:8-9, and 2:1). Under the Old Covenant, people could not be cleansed of sin-consciousness (Heb 10:1-4); while under the New Covenant, people's sins and iniquities are remembered no more (Heb 8:12 and 10:17), and their guilty consciences are cleansed (Heb 10:22).

What does correlate between the Old and New Testament is that in Exodus chapter twelve where God sent the Angel to kill the first born of every household. The Israelites were told to put blood on the door posts so the Angel would pass over that home. In each of those homes who had sprinkled the blood of a lamb on the door posts were varying degrees of holiness, growth, and sinfulness in following God. The Angel did not look at the people inside the home, the Angel only saw the blood and passed over that home. It was not about inspecting the people, it was only seeing the blood. The same is true in the Old Testament when a person brought their sin sacrifice to the Preist, the Preist did not inspect the people for their blemishes but inspected the lamb that they brought if it was perfect and without blemish. It is the same today, God looks at the blood of Jesus that covers us and see's us righteous. Which means that if your trying to be justified by anything other than faith in Jesus Christ then you are not believing the true Gospel. His blood and only His blood covers our sin, it is not any works that you do at all.

Receiving by law and receiving by promise are opposites. Law involves effort (works). Promise provides as a gift (grace). We are either saved by works or by grace, but not a combination of the two (Ro 11:6). Paul stated the doctrine of justification by grace through faith so clearly in his writings that any person who claims to believe the Bible has to acknowledge this truth. However, one of Satan's cleverest deceptions is to take a truth and add to it until it is no longer the truth. Lest that happen with this doctrine of grace, Paul stated emphatically that we cannot combine anything with God's grace as a requirement for salvation.

In the same way that gasoline and water don't mix, so grace and works will not mix. Justification has to be all works or all grace, but not a combination of the two. All religion is based on what you do or sacrifice. The new covenant with Jesus Christ is based on what Jesus Christ has done and sacrificed. Still, an abundance of religious people today cannot accept the fact that all we have to do is to believe to receive God's grace (Ro 5:2). Faith is our admission, or ticket, into the grace of God. No one is allowed in without a ticket. Our own good works won't grant us admission. God's grace can only be accessed by faith.

Ephesians 2:8-9
8 For it is by grace you have been saved, through faith--and this not from yourselves, it is the gift of God--
9 not by works, so that no one can boast.
