I don’t like the word conversion, but I use it because so many use this word when one comes to faith in Yeshua (‘Jesus’). Saul already feared Yehovah, and he believed in Him, having the greatest fervency for the Torah (which he never lost). He did not have a covering for sin, however, and he and his friends were ‘hit men’ on assignment to find, arrest, try, then slaughter all Jewish folks who demonstrated faith in Yeshua.
