Many false doctrines are a result of misunderstanding covenants. The improper use of the Word has eternal consequences (Galatians 1:8-9), so it’s imperative that we properly divide the Scriptures (2 Timothy 2:15).
God established a covenant with Israel after Egyptian bondage (Exodus 19:1-6). If they would be faithful, God would care for them with great gentleness (Exodus 19:7-8).
On earth, Jesus embarked on a mission to fulfill the old covenant (Matthew 5:17-18; Luke 24:44). The Law of Moses wasn’t a failure, just temporary (Jeremiah 31:31-34). God’s plan led to the cross so the old covenant could be nailed to the tree (Colossians 2:11-14).
While the Old Testament is no longer authoritative, it retains great importance as a teacher (Romans 15:4). We’re unable to grasp the meaning of the New Testament without a knowledge of the Old. It’s indispensable to God’s people today.
The covenant confusion today is inexplicable when we consider that the New Testament has an entire book called Hebrews that addresses the subject in-depth.
Jesus became the “Mediator of a better covenant, which was established on better promises” (Hebrews 8:6, NKJV) because the first covenant became obsolete (Hebrews 8:13). Christ became the High Priest of this new covenant through the shedding of his blood because the offerings of bulls and goats became insufficient (Hebrews 9:11-15).
Remission of sins is found only through the blood of Christ (Hebrews 10:11-25) and we’re added to the Lord’s Church, the body of Christ (Acts 2:38,47; Ephesians 1:22-23; Romans 6:3-4). Christ is now our justifier, not the Law (Romans 3:21-26).
What happened beforehand is instructive but it remains in the past. We live under the New Covenant exclusively and we must study it as a man dying of thirst (John 4:10-14). Trust God today (Hebrews 11:6) and live daily in his light (1 John 1:7).
