What life?
Christians in the first century lived Godly lives. They cared for their poor. They taught others. They sent out preachers where they could not go. With simplicity of faith and fervor there was no need of centralization.
Without conventions, councils, synods, headquarters on earth, or other inventions of man, the gospel was preached thoughout the world in a short time.
Colossians 1:23 "if indeed you continue in the faith, grounded and steadfast, and are not moved away from the hope of the gospel which you heard, which was preached to every creature under heaven, of which I, Paul, became a minister."
These disciples were known as Christians. They wore no sectarian names to divide them.
Acts 11:26 "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."
I Peter 4:16 "Yet if anyone suffers as a Christian, let him not be ashamed, but let him glorify God in this matter"
Their religion was not sensual or materialistic. They sought to impress God with the only thing that ever impresses Him - contrite obedience.
I Samuel 15:22 "Has the LORD as great delight in burnt offerings and sacrifices,
As in obeying the voice of the LORD? Behold, to obey is better than sacrifice, And to heed than the fat of rams."
Their appeal was not social or recreational. They offered the gospel to a troubled world for it was God's power to save. Any other appeal was beneath the one to the Lord.
Romans 1:16 "For I am not ashamed of the gospel of Christ, for it is the power of God to salvation for everyone who believes, for the Jew first and also for the Greek."
