Acts 2:1-4
On the day of Pentecost, seven weeks after Jesus’ resurrection, the believers were meeting together in one place. 2 Suddenly, there was a sound from heaven like the roaring of a mighty windstorm in the skies above them, and it filled the house where they were meeting. 3 Then, what looked like flames or tongues of fire appeared and settled on each of them. 4 And everyone present was filled with the Holy Spirit and began speaking in other languages, as the Holy Spirit gave them this ability.

First evidence of the Church is at Pentecost.  The Church, born at Pentecost, is called the Body of Christ (Colossians 1:18). Jews and Gentiles are united.  Events in the ministry of Jesus were essential to the establishment of the Church.  Certain things had to take place.  They are the resurrection and ascension of Jesus to become head of the Church (Ephesians 1:20-23 and 4:7-11).  The Church, with the believers as the body and Christ as the head, did not exist until after Christ ascended to become its head.  And it could not become a functioning entity until the Holy Spirit provided the necessary spiritual gifts and power. The Church is distinct from Israel in that it is a unique relationship between Jews and Gentiles called one new man in Ephesians 2:15.   During this current age, God is saving a remnant of the two previous entities (Israel and Gentiles) and combining them into a third new entity-the Church.  This unity of Jews and Gentiles covers only the Church age, from Pentecost to the Rapture.  There has never been an easier time to come to know God than during the current time we live.  If you not part of the Body of Christ, there is still time, but this Age is coming to end very rapidly. Accept the resurrected Christ as your Lord and Savior and become a part of His body.

Have a God Day!
