The New Testament Church in Its First Century was Full of Vigor and Grace.
The witness of the apostles concerning Christ's life and teachings, His sacrifice and resurrection, activated the vision of all believers and inspired the church to evangelize the entire world rapidly.
The success of the gospel was a result of the Holy Spirit's work through the lives of believers. The apostles were of one accord. "Christ filled their thoughts; the advancement of His kingdom was their aim. In mind and character they had become like their Master, and men 'took knowledge of them, that they had been with Jesus.' --The Acts of the Apostles, p. 45.
The power and gifts the apostles received at Pentecost gave efficiency to their evangelistic efforts. The promise that this power will be revived among us in these last days makes our study of the apostolic church more meaningful. "Before the final visitation of God's judgments upon the earth there will be among the people of the Lord such a revival of primitive godliness as has not been witnessed since apostolic times.'--The Great Controversy, p. 464.
