This is the argument many Christians have against the Messianic Movement. However it is based completely on misunderstanding. Messianics DO NOT believe the law of Moses ever saved anyone! Do we need a crash refresher course on The Gospel? Genesis chapters 1-3 tell the story of the fall of humanity (Ha Adam). Therefore, just as sin entered the world through one man, and death through sin, in this way death spread to all men, because all sinned. ~~Romans 5:12 Through the sin of one man we are all born under the law of sin and death. For all have sinned and fall short of the glory of God. ~~Romans 3:23. So I discover this principle: When I want to do what is good, evil is with me. For in my inner self I joyfully agree with God’s Law. But I see a different law in the parts of my body, waging war against the law of my mind and taking me prisoner to the law of sin in the parts of my body. What a wretched man I am! Who will rescue me from this dying body? I thank God through Jesus Christ our Lord! So then, with my mind I myself am a slave to the law of God, but with my flesh, to the law of sin. ~~Romans 7:21-25 Yeshua came to deliver us from this law; the law of sin and death, not His own law! "Think not that I came to destroy The Law or the Prophets; I came not to destroy, but to fulfill. For verily I say unto you, till heaven and earth pass away, one jot or one tittle shall in no wise pass away from The Law, till all things be accomplished" ~~Matthew 5:17-18. "If you love me, keep my commandments." ~~John 14:15.
When the Pharisees heard that He had silenced the Sadducees, they came together. And one of them, an expert in The Law, asked a question to test Him: “Teacher, which command in the law is the greatest?”
He said to him, “Love the Lord your God with all your heart, with all your soul, and with all your mind. This is the greatest and most important command. The second is like it: Love your neighbor as yourself. All The Law and the Prophets depend on these two commands.” ~~Matthew 22:34-40. So love is the fulfillment of God's commandments. If you keep the 2 love commandments are you not following God's Law? Do you do it because you think it saves you? Heaven forbid! We do it because we love the LORD!
