The document discusses the differences between the Old (Mosaic) Covenant and the New Covenant. The Old Covenant was established through animal sacrifice, marked by circumcision of the flesh, and was unable to produce true obedience. The New Covenant was established through Jesus' sacrifice, is marked by circumcision of the heart, and gives believers the power of the Holy Spirit to know God, obey His law, manifest grace, produce "rivers of living water", and do greater works than Jesus. To be under the New Covenant is to experience this transformation and empowerment by the Spirit.
