Did Jesus teach conformity to Law or grace and mercy through faith? Should we teach others to conform to Law or the Spirit?
Jesus entered Time under Law (Galatians 4:4) and came to proselytize those under Law in the freedom of grace and mercy through faith (John 3). If the Law was the path to righteousness and holiness, Jesus would not have needed to suffer and die for our sin (Galatians 2:21).
The Law Covenant is NOTHING but a definer of sin and culpability (Romans 3:20) and a Tutor to point the children of Israel to their need for a Messiah and once Messiah came and fulfilled the righteous mandates of the Law for us, we are no longer under Law but under grace through faith in Jesus via the Holy Spirit (Galatians 3:24; Romans 6:14).
People intuitively know the law as it is written upon their heart by our Creator at conception (Romans 2:14-15; Genesis 1:26-28); therefore, what people actually need in their life is redemption by faith in Jesus and the indwelling Holy Spirit guiding them in God's will, the moral law, through the conscience via sanctification; therefore, our efforts as servants of God the Father must be to point others NOT to conformity to Law in legalism but faith in Jesus and allow the anointing of the Holy Spirit to create in them the New Man and the New Woman seeking obedience to the Father's will out of love for God through sanctification and NOT in fear of law and punishment.
Deterrence via fear through legalistic law keeping is easily rationalized away by the sin-nature as evidenced by Israel's repeated failures to please the Father through law keeping; Israel's repeated rejection of the Father's grace through faith are examples of legalistic futility; therefore, Jesus provides the only Way (John 14:6) to the Father's heart (John 6:29); that is, trusting in Jesus as Lord (John 3); receive the indwelling Holy Spirit (Ephesians 1:13-14); receive the "new nature" integral with the "new birth" (John 3; 2 Corinthians 5:17) and walk in intimacy with the Father via obedience to the Spirit via the conscience via sanctification as the Spirit prepares you for service in the New Jerusalem (Galatians 5:16). This is God's will for your life as you become His family, His child, His beloved, forever, through faith in the Son as your Messiah via covenant promise (Hebrews 8:12).
Vain attempts at conformity to letters kills the soul but obedience to the indwelling Holy Spirit provided the redeemed in Jesus is life and peace, forever (2 Corinthians 3:6).
