What is the difference between Israel, the Gentiles, and Gog and Magog.

You asked: We as gentiles, how do match with Israel? Also Israel were the children of god or servant of GOD. What is the difference between servant of GOD and children of GOG"

Answer: Israel were the people God chose to be His nation, and to show the world that God is real. These Israeli people call all non-Israeli people by the term 'Gentiles'. All nations other than the Jewish Israel are thus included in the term Gentile.

God intended for the people of Israel to be the ones to spread the message of God's love to all nations. As such they would be the Servants of God. They did not do that and became proud that they were the chosen people, and thought God was only for them.

Jesus told them that God loves all the people of the world, in John 3:16. He took a band of 12 Jewish Israeli people and used them to start sharing the message of Salvation with others. He showed Peter that non-Jews were also to be saved and filled with the Holy Spirit, (Acts 10:28-35) and then used Paul, to take the Gospel to the Gentiles.

You can be a child of God, and yet not serve God by sharing the good news of Salvation to others. A servant obeys his masters orders, and Jesus said we were to take the Gospel to all nations Matthew 28:18-19.

You end your questions asking about children/servants of God, and children of Gog.

Believers in Jesus are children and servants of God, and there are now many Israeli believers in Jesus.

The Children of GOG are mentioned as nations that will come against Israel in the last days.

Schofield reference notes on the Bible refers to Ezekiel 38:2

"Gog: The primary reference is to the northern (European) powers, headed up by Russia, all agree. The whole passage should be read in connection with (Zec_12:1-4); (Zec_14:1-9); (Mat_24:14-30); (Rev_14:14-20); (Rev_19:17-21); "gog" is the prince, "Magog," his land. The reference to Meshech and Tubal (Moscow and Tobolsk) is a clear mark of identification. Russia and the northern powers have been the latest persecutors of dispersed Israel"

I would encourage you to read Ezekiel chapter 38. This is thought to be an end time prophecy of a final invasion of Israel just before Jesus returns to set up His kingdom in Jersusalem as seen in Revelation chapter 21.

Thank you for asking.
