Bible Verses About Conversion To Christianity

Early Christian writings teach that conversion meant turning from idols, sin, and old ways to faith in Christ, baptism, and a changed life. Justin Martyr, Ignatius, Tertullian, Origen, Irenaeus, Cyprian, Hermas, and the Apostolic Constitutions all speak this way in different forms. The evidence is broad across the 2nd and 3rd centuries, and it connects conversion with repentance, baptism, confession of Christ, and new conduct.

Some texts also stress that conversion could be sudden, while others speak of it as a process or even as the work of grace. A few items are only background or use the word in a different sense, so they are not central to the main claim.
