The Old Covenant was flawed because it could not perfect those who were under it nor did it promise to provide the enabling power to keep it. Not so with the New Covenant. This covenant not only has the power to perfect people through the blood of Christ, but it promises enablement to those with the Spirit. Pastor Josh uses the analogy of dishwashers to help us grasp these important and deep concepts.
In an encounter with Nicodemus, Jesus seeks to expose what the most important issue is: the need for rebirth. Like all of us, Nicodemus was preoccupied with the things on the surface, but real change and real relationship with God starts with a new heart.
