Why A New Covenant if the First was Perfect?

This all together is a confusing topic to tackle, and somewhat difficult to explain or gather because of the way people/believers interpret the law and the bible. What is a Covenant? It is promise or oath before and with God that sets forth his law and promise. In laymen terms, God’s Covenant is broken into two sections: The Old Covenant (Old Testament) and the New Covenant (New Testament). Sometimes also known as the Covenant of Works (O.T.) and the Covenant of Grace (N.T.).

The Perfection of God's Law

The Bible confirms over and over again that the law and his covenant are and is perfect. "The Law of the Lord is perfect" (Ps. 19:7). God is a perfect being who made the perfect law. As for God, his way is perfect; the word of the LORD is flawless. He is a shield for all who take refuge in him. Thus in inferring from scripture it is natural to assume that not only is God’s law perfect, but so is his covenants.

The whole convental law is perfect, because all ordinances and commandments by God are Good. So according to Christianity there is no flaw in God’s law because it is and remains perfect. God’s Law and Covenants is still and forever Perfect, and all imperfections are a reflection of a sinful and fallible man who lacks the capacity to comprehend and follow them.

The Limitation of the Law and the Fallibility of Man

So the question is, if God’s convental law is perfect, why would he need more than one? Biblically and theologically speaking the reasoning & answer is very simple. Man is not perfect and deeply flawed and fallible. Thus in speaking the fault is not in the law, but the fallible and sinful man. The flaw was in the people for the law cannot save because the heart of man is deceitfully wicked above all else and seeks only his own gain.

God’s perfect Law could not declare the sinner righteous; it could only condemn and execute him. Law can only condemn the law breaker; it cannot save him. God gave His perfect Law to demonstrate to sinners that we cannot stand before Him on the basis of our own merit…on law ground. The sinner must not seek his salvation on the grounds of law keeping, for, even if he kept the entire law and committed just one infraction, the Law would justly demand his doom (James 2:10).

The Purpose of the New Covenant

In evaluating the answer of why a new covenant we learn that the simple answer is that the new covenant is set forth by God to serve a new purpose. Which is too bring Man closer to God. The reason for establishing a new covenant is for the benefit and mercy of mankind. The Biblical story goes as such; that God sent his son Jesus into the world to die for all sins, such that he could establish a new covenant for all eternity, because all of the previous covenants before hand lacked the full capability to forgive sins, get man back into right fellowship with God and save man from damnation.

The only reason why there are multiple laws and covenants is because when the Priesthood changes, so does the law. No, the sinner can only approach God on the grounds of God’s Grace. "The Law is good, if a man use it lawfully" (1 Timothy 1:8).

Covenant Type	Theological Designation	Primary Purpose and Capability
Old Covenant	Covenant of Works	To demonstrate to sinners that we cannot stand before God on our own merit; it can only condemn and execute.
New Covenant	Covenant of Grace	To forgive sins, get man back into right fellowship with God, and save man from damnation for all eternity.
