In the ancient Greek city-states, it was the sound from a herald’s blown trumpet that called forth/summoned the different groups of Greek citizens to their own ekklesia (a word in the ancient Greek cultural that depicted the basic idea of an “assembly”). Every different ekklesia was held in a local community meeting place where each assembly (ekklesia) of Greek citizens discussed their own city-state’s various political concerns. These facts are why if the last days alive believers in Christ Jesus are going to be alert AND prepared for God’s promised last-trumpet summons, which will call them to come up hither, then it is vital that every one of today’s believers in Christ Jesus takes part in the process of recapturing the first-century followers of Christ’s cultural commission of going into the world as they knew it to both evangelize their world and disciple all the NATIONS. For the Word of God is crystal clear about this display of a global influence being exactly what God always intended for every one of His Household of Faith children to achieve.
The “church” is the globally recognized spiritual body of loving, caring, born again, saved believers in Christ over whom Christ is the Head and the Lord, which gives Him the authority and the power to add new believers daily to His spiritual body of “called out” Christians who have assembled in the public and private places located throughout this entire world.
