"Do not learn the way of the gentiles"(Jer10:2). Who are they? And what's role of the gentiles?

Shalom! Welcome to Catatan Josephine. Some of us asked me who are the gentiles, and what role the gentiles in God's plan?. Major portion of the scriptures are bible prophecies. From genesis until revelation. Its God's master plan. He is still the same God. He never withdraws His words, promises. With Holy spirit that Jesus gave to us, we be able to understand God's mind. He talks to us, walks to us every step of the way so we become full mature. Have a good understanding about what's right and wrong, good or evil. This is His will. Jesus wants us to separate from this world. Dont hold anything from this world. Take up your cross and follow Him. Let go all form of tradition that's not from God and keep all His commandments.
