Religionist said: “It’s so weird when so called believers try to argue against following the Lord’s commandments.”
Christian response,
Those who are “believers,” having been born again into the New Covenant, understand the process of “commandment” keeping as it relates to the Spirit’s work via the “new creation” in Jesus (2 Corinthians 5:17).
If one desires to honor Messiah’s commandments, they must first honor HIM and the Father through faith believing that Jesus is Messiah who died for them and was resurrected for them (Romans 10:9-10) and it is by “believing” that one receives the indwelling Holy Spirit as the Seal and Guarantor of New Covenant relationship (Ephesians 1:13-14).
It is then, by the anointing of the indwelling Holy Spirit, that the redeemed, the new creation, begins a journey of daily sanctification (a setting apart from the World) and the Holy Spirit begins to produce divine fruit through the redeemed (Galatians 5:16-23) and it is this divine fruit that fulfills all law; both, codified and spiritual and it is that fruit that pleases the Father and proves one to be a legitimate disciple of Jesus (John 15:8).
Christianity is NOT about pursuing laws, days, diets, traditions, clothing, but Christianity is about a personal, divine, relationship with the Father through faith in the Son and life anointed by the indwelling Holy Spirit, walking in peace with Elohim, producing fruit that furthers and honors the Kingdom. Christians serve the Spirit, not Moses.
