Paul who was then Saul was converted on the road to Damascus when he was traveling to persecute the Christians.
Emperor Constantine converted after witnessing the sight of a cross in the sky along with his entire army
Writer Augustine converted after hearing a child's voice say "take up and read"
Explanation:
For Paul
Famously converted on the road to Damascus, he travelled tens of thousands of miles around the Mediterranean spreading the word of Jesus and it was Paul who came up with the doctrine that would turn Christianity from a small sect of Judaism into a worldwide faith that was open to all.
For emperor Constantine
Constantine is the first Roman Emperor to convert to Christianity. He did so after witnessing the sight of a cross in the sky along with his entire army
For writer Augustine
In late August of 386, at the age of 31, having heard of Ponticianus's and his friends' first reading of the life of Anthony of the Desert, Augustine converted to Christianity. As Augustine later told it, his conversion was prompted by hearing a child's voice say "take up and read"
