The Bible: Old Testament vs. New Testament

I want all my believing friends to know this, that the Bible is a unified book, there are no differences between the Old Testament (OT) and the New Testament (NT). 

In many ways, are the two testaments complementary. 

  • The OT provides the history of a people and we need that history; the NT focus is on a Person, and we need that too. 
  • The OT is foundational; the NT builds on that foundation with further revelation from God. 
  • The OT establishes principles that are seen to be illustrative of NT truths. 
  • The OT contains many prophecies that are fulfilled in the NT. 
  • The OT shows the wrath of God against sin (with glimpses of His grace) that we see also mostly in the book of Revelation. The NT shows the grace of God towards sinners (again with glimpses of His wrath).

The OT lays the foundation for the coming of the Messiah who would sacrifice Himself for the sins of the world (1 John 2:2). In the NT Christ is revealed; it records the ministry of Jesus Christ and then looks back on what He did and how we are to respond. What did he do without him having to fulfil scriptures?

And both testaments reveal the same holy, merciful, and righteous God who condemns sin but desires to save sinners through an atoning sacrifice. In both testaments, God reveals Himself to us and shows us how we are to come to Him through faith (Genesis 15:6; Ephesians 2:8).

Pastor understands that the OT is full of shadows for/of the NT, but it does not do justice to law of God to disregard the OT completely. Yes, the priesthood changed and all that’s to do with it and so were Moses’ laws removed, “Blotting out the handwriting of ordinances that was against us, which was contrary to us, and took it out of the way, nailing it to his cross;” but the laws of God remains intact. These were never changed because God never changes. For grace to be grace it has also to embrace the law, and the prophets. “For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled” Matthew 5:18. These will remain intact.

Ask yourself why God had to send his son? Was it that through him he would abolish the law or establish it? Why would he want to destroy all those fundamental principles, and the history? What came he to serve?

God bless,
