Hi OP,
Jesus is the complete fulfillment of the OT Law that was given to TEACH mankind the ways of the KINGDOM OF GOD. The Law convicted mankind of sin. Sin ultimately destroys and therefore needs atonement.
In the Old Testament a blood sacrifice was accepted as payment for sin.Chiefly because blood cleanses.... as well it does our physical system and is the physical life force for humans.
However, Jesus became the PERFECT BLOOD SACRIFICE for any sin that we have ever committed, providing we receive His precious gift. When we accept His payment, we accept Him.
He assures that He is 'THE WAY THE TRUTH AND THE LIFE, AND NO ONE COMES TO THE FATHER BUT BY HIM'.That is the condition of the contract/covenant.
For believers,Heaven is the final destination where sin is nonexistant.
Jesus dwelt among the outcasts of His day...He loved them and forgave them and healed them when they reached out to HIM.
Today is no different. He is the God of Love and willingness to forgive.
The Bible is TRUTH and is revealed by the Holy Spirit to those who reach out in sincerity. The Prophecies alone read like a news article in our own time.
His Name has POWER beyond any other name. He is coming back and will fulfill all prophecy...down to the 'last jot and tittle'....
He awaits you to prove His TRUTH...
God Bless
