For I the LORD do not change; therefore you, O children of Jacob, are not consumed.
-Malaki 3:6 ESV

Warrior;

God is immutable, He does not change! There is one GOD(Dt 6:4); the God of the old testament and the God of the New testament are the same, the difference is Jesus!

The Old Testament consists of three types of Law; Ceremonial, Civil and Moral. When Jesus came He became the fulfillment of the Ceremonial or Sacrificial law. The Civil law was HOW TO live in modern society- that has changed and HONOR GOD, However, the Moral laws, founded in the 10 commandments, NEVER CHANGE! God does not evolve!; He still feels the same way about sex outside of marriage, men laying with other men, and neglected those in need.

Conduit, “Don’t suppose for a minute that I have come to demolish the Scriptures—either God’s Law or the Prophets. I’m not here to demolish but to complete. I am going to put it all together, pull it all together in a vast panorama. God’s Law is more real and lasting than the stars in the sky and the ground at your feet. Long after stars burn out and earth wears out, God’s Law will be alive and working.(MSG Mat 5:17-18)
