Your Salvation, and My Salvation is guaranteed by GOD’s promises to Abraham, and not on the Mosaic law, given to Moses 430 years later on Mount Sinai, after the children of Israel were freed from slavery in Egypt.

The covenant conditional Mosaic law, began with Moses, and ended with the death of Jesus, who declared "IT IS FINISHED". JESUS IS the Christ, GOD’s Jewish Rabbi, the Word of GOD, the Son of GOD, and our precious Savior.
In Matthew 5:17, and 18, Jesus said:
“Think not that I am come to destroy the law, or the prophets… I am not come to destroy… but to fulfill.”
“For verily I say unto you, Till heaven and earth pass, one jot or one tittle shall in no wise pass from the law, till all be fulfilled.”

The Mosaic law ended the day the Promise Seed of Abraham accursed died on the cross, and Christianity through Faith begin the day Jesus Arose from the Dead!
Christianity began on Resurrection Day, when the crucified Word of GOD, got up from the grave, and walked, and talked, and ate, in his new glorified body.
