Why We Don't Go Back to Moses
"If we truly love God, shouldn't we keep the Law of Moses—sabbath, feasts, dietary laws?"

The New Testament plainly defines the Law now that Christ has come.

Read the Scriptures on the matter:
• "The ministration of death" (2 Corinthians 3:7, 9): Speaking of the Ten Commandments, Paul says it could only condemn, never save. Its glory was "done away" (v. 11). It is "the letter" that "killeth" (v. 6)—demanding obedience without giving the power to obey.

• "Our schoolmaster" (Galatians 3:24-25): "Wherefore the law was our schoolmaster to bring us unto Christ... after that faith is come, we are no longer under a schoolmaster." It was "added because of transgressions, till the seed should come" (Galatians 3:19). It was a temporary guardian, not our permanent rule.

• An unbearable yoke (Acts 15:10): Peter asked the council, "why tempt ye God, to put a yoke upon the neck of the disciples, which neither our fathers nor we were able to bear?"

• Abolished & nailed to the cross (Ephesians 2:15, Colossians 2:14): Christ "abolished in his flesh the enmity, even the law of commandments." He was "blotting out the handwriting of ordinances... nailing it to his cross." These were merely "a shadow of things to come; but the body is of Christ" (Colossians 2:17).

• Disannulled (Hebrews 7:18-19, 8:13): "there is verily a disannulling of the commandment going before for the weakness and unprofitableness thereof. For the law made nothing perfect, but the bringing in of a better hope did." The first covenant is "old" and "ready to vanish away."

• Bondage (Galatians 4:9-11, 4:30-31, 5:1): Sliding back into observing "days, and months, and times" is turning to "weak and beggarly elements." We are children of the freewoman, not the bondwoman. "Cast out the bondwoman... Stand fast therefore in the liberty wherewith Christ hath made us free."

You cannot be an heir of Hagar and Sarah at the same time. You cannot mix Law and grace. You must choose.

Believers are under grace (Romans 6:14, 10:4): "For ye are not under the law, but under grace." "For Christ is the end of the law for righteousness to every one that believeth."

This is not a license to sin (Romans 6:15): "shall we sin, because we are not under the law, but under grace? God forbid." We are "under the law to Christ" (1 Corinthians 9:21) and are called to "fulfil the law of Christ" (Galatians 6:2) by love.

Under Moses, men lacked the power to obey. But "the law of the Spirit of life in Christ Jesus hath made me free from the law of sin and death" (Romans 8:2). We do not stand under Moses; we stand in Christ.

Do not trade the substance for the shadow. "Stand fast therefore in the liberty wherewith Christ hath made us free" (Galatians 5:1).

It’s one of the most clearly taught doctrines of the bible. If you miss this, you are a deceived fool or a deceiver.
