The Apostles had lived with Jesus on a daily basis for three and a half years learning from Him many things about the Kingdom of God and how to live life as Kingdom citizens.
Christ actually spent his last forty days on earth after His resurrection teaching them “the things pertaining to the Kingdom of God.” (Acts 1:1-7 (KJV)
On the day of His ascension from the Mount of Olives, He commanded them they should not depart from Jerusalem but wait for the promise of the Father. (Acts 1:4 and 5 (KJV)
Acts 2:42-47 shows us how God met the needs of these new followers of Christ under what is called the “Apostles Doctrine.”
God immediately set up His Kingdom Economy through the Apostles Doctrine on the day of Pentecost when the Apostles, along with about three thousand souls, received the Promise of the Father.
Acts Chapter 2 states that all who believed were steadfast in praying, breaking bread, and sharing their plurality with one another. Because of their new belief in the Messiah these people possibly had been marginalized by the Temple authorities. However somehow under God’s Kingdom Economy or the Apostles Doctrine all the believers had their needs met and their numbers began to increase.
From then on we see in the Book of Acts various places where these followers of the Way, “sold their property and houses” for the advancement of the Kingdom.
Today as we seek first the Kingdom of God and His righteousness we may begin to see a clearer vision of what Jesus meant about the life style of the Kingdom of God which Jesus came to introduce to mankind.
Christ did not come to move His gospel by forming a regimented military type of operation, but He came to make available for his followers a life style of Kingdom Living.
