I will give you a new heart and put a new spirit in you; I will remove from you your heart of stone and give you a heart of flesh. And I will put my Spirit in you and move you to follow my
decrees and be careful to keep my laws.
One of the most frustrating experiences we can have is to know to do right but always end up doing wrong. All of us have been there, part of us wants to change but we find ourselves falling back down that slippery slope time and time again. Arrrggghhh!!! That was the basic problem of the law in the Old Testament or any religious system that is ultimately based on human will power to follow them. The Old Testament law as well as any other version of works or principles is doomed to failure. It’s not that the law was flawed, we are. We don’t have the capacity in our fallen human state to do the good even when we really want to change. The solution, the new birth and the power of the Spirit. This new work of God goes to the very depths of our being, our heart. This is what is changed in the New Testament, we now have the power and the desire to live a different kind of life. Here is how Andrew Murray describes it.
“In contrast to the Old Covenant, the God-given power that enables the people to stay within His law is the distinctive feature of the New Covenant. But why does the truth of the New Covenant so seldom become a reality in the life of a believer? The answer is quite simple: It is not preached or believed, and the fulfillment of it is not felt in the believer’s life. Paul is an example of the fulfilling of the New Covenant in a believer’s life. The same anxious person who cries out that the power of sin holds him captive, shortly thereafter thanks God that he has, in Jesus Christ, through the Spirit that gives him life, been set free. Why is it that so few people can testify to the truth of this? God links His promises to our faith—however difficult the truth may be for the human mind to fathom. His promises become operative when we believe.”
How does this change take root in us? If you are born again the work has begun. Your cooperation comes through saturation in God’s written word and learning to draw near to Him by faith in His blood. This becomes our way of life. Suddenly we see the change in us, we find ourselves saying, “I delight to do your will Oh God!!!”.
