Chapter 8 of Hebrews elaborates on this new covenant innaugaurated with Christ. Now, God’s law can be written our minds and hearts, and we can “Know the Lord” and experience the mercy of God in a new way (Heb. 8:11).
The new covenant of Christ accomplishes something the old covenant of Moses never could, and its effectiveness doesn’t depend on our actions. Israel proved that humans under their own power cannot “continue in the covenant” (Heb. 8:9).
This new covenant in which forgiveness reigns and our souls are transformed is enacted completely on the basis of Christ’s faithfulness and the promises of God the Father.
Is it any wonder that we are spiritually formed by this new freedom and intimacy with the Creator of the universe? How can we not be changed when Jesus, through whom the world was created, is praying for us constantly (cf. Heb. 1:2)?
Just knowing this truth causes a change in my mind and spirit.
