Why Jesus and the Holy Spirit are infinitely superior to Moses…
The Holy Spirit’s work in the New Covenant as He indwells the faithful (Ephesians 1:13-14; John 14:16), those possessing a new nature in Jesus (2 Corinthians 5:17) and walks them daily in the Father’s will through sanctification via the conscience (Galatians 5:16), the Spirit provides an infinitely superior form of obedience to the Father’s will than letters scratched upon parchment by Moses which are subjective and easily disregarded by the seared conscience of the natural man enslaved to a sin-nature (Romans 8; 1 Corinthians 2:14).
Law is for the lawless (1 Timothy 1:9) that judgment, adjudication, might manifest with due process (Revelation 20:11-15) but the faithful in Jesus don’t dwell on letters in cold, unyielding, stone but the Christian thrives on the Holy Spirit who gives life through His faithfulness to secure and teach and sanctify those who love Jesus and honor the Father by faith in the Son (John 14:16; 1 John 2:27).
The New Covenant is infinitely superior to the Old Covenant of Law as the letters of Moses kills the soul in condemnation void atonement (Romans 3:20) but the Spirit gives life through grace and peace through wisdom and knowledge granted by covenant promise as the Spirit methodically conforms the faithful into the obedient image of Jesus Christ as He prepares the Father’s children for service in the New Jerusalem (Hebrews 8:12; Romans 5:1; Romans 8; 2 Corinthians 3:6).
If one desires true LIFE and PEACE with our Heavenly Father, there is no other Way to achieve that covenant relationship but through Jesus as Lord (John 14:6; Romans 5:1) with the Holy Spirit indwelling you and walking you daily in sanctification with patience and love and mercy (Galatians 5:16). The OLD condemns void atonement (Romans 3:20) but the New gives life through peace with the Father via faith, forgiveness, redemption, in Jesus and the Spirit as our wisdom and truth in sanctification (Romans 5:1).
