First, allow me to share the origin of the word Christian. It first came on the scene in history in the city called Antioch. Then Barnabas departed for Tarsus to seek Saul. And when he had found him, he brought him to Antioch. So it was that for a whole year they assembled with the church and taught a great many people. And the disciples were first called Christians in Antioch. You see, this was truly stated, but not a statement of truth. The people of Antioch named them "Christians", God didn't; and neither did their Lord and Savior Jesus the Christ. From there, the name became infectious. The people gave them that name because they worshiped and followed Christ's teachings. Please understand this statement: if people name you, they will define you.
From that point on, individuals who claim to believe and follow Jesus' teachings were called "Christians". Then Agrippa said to Paul, “You almost persuade me to become a Christian.” This is when saints behavior represented the Kingdom. From that point on, many who followed Christ's teaching began to embrace that name the people of Antioch gave them. Yet if anyone suffers as a Christian, let him not be ashamed, but let him glorify God in this matter. Nowadays, most who say that they believe in God, claim to be a "Christian" regardless of their principles and behavior.
Kingdom Citizens on the other hand, live by God's Constitution and most of all, they are filled with His Spirit. Jesus told His disciples to stay in that one place until the helper came. And being assembled together with them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, “which,” He said, “you have heard from Me; for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.” Where do you think the Holy Spirit comes from? The Kingdom of God--from the Lord God Himself. His Spirit makes us genuine citizens in good standing with the King. Why? Because Kingdom Citizens live by every Word of God, and they worship His Son King Jesus. Christ's reply to the devil was this: ...“It is written, ‘Man shall not live by bread alone, but by every word that proceeds from the mouth of God.’”
Remember, Kingdom Citizens live by God's Word, which are His laws and principles; not by religious traditions and customs of men. They read and study the King's Word every day to encourage them in their purpose while they are on this planet.
