The Covenant of Law, its Purpose…
The Law defines God’s righteousness and the Law defines your sin, your culpability before God but does NOT provide you atonement or reconciliation with God the Father as our sin creates a chasm between God and sinful mankind (Romans 3:20-23). The Law was meant to be our Tutor, our Schoolmaster (Galatians 3:24-26), to point us to Jesus and show us our need for Jesus by faith as our Intercessor, the One who kept the Law for us in perfection (John 8:46) and offers you and me HIS righteousness imputed into our lives by trusting in Him as our Lord, Messiah, Savior (2 Corinthians 5:21; Genesis 3:21).
It is ONLY by believing and trusting in Jesus as your Lord who died for you (Romans 10:9-10) that initiates covenant relationship with the Father (John 3:16-18; 1 John 2:23) and once that relationship is established and you have received the indwelling Holy Spirit as Guarantor of covenant relationship (Ephesians 1:13-14), your obedience to the Commandments of Christ, the will of God for your life, becomes relevant (Galatians 5:16) as it is your works of obedience that validate your faith as being life saving, true, faith (James 2:18). Your obedience to God’s will subsequent to establishing covenant relationship by faith in Jesus as Lord verifies that you are indeed a “new creation” in Christ (2 Corinthians 5:17; Galatians 5:16).
The most relevant thing in this LIFE constrained by Time and physics is trusting in Jesus Christ as your Lord believing that He died to pay your sin-debt; therefore, study the word of God to show yourself a good disciple, a faithful servant of the Lord (2 Timothy 2:15) and everything else will begin to fall in place as the Holy Spirit will become your Teacher (1 John 2:27).
