Jesus Christ saved Saul of Tarsus, a very zealous Hebrew Pharisee, nearly two millenia ago. When Jesus saved Saul from sin and eternal death in hell, he gave him the Holy Spirit and a clean new heart so he could obey the Lord and become the faithful Apostle Paul who wrote much of the New Testament of the Holy Bible.

Moreover, brethren, I declare unto you the gospel which I preached unto you, which also ye have received, and wherein ye stand; By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain. For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; And that he was buried, and that he rose again the third day according to the scriptures: And that he was seen of Cephas, then of the twelve: After that, he was seen of above five hundred brethren at once; of whom the greater part remain unto this present, but some are fallen asleep. After that, he was seen of James; then of all the apostles. And last of all he was seen of me also, as of one born out of due time. For I am the least of the apostles, that am not meet to be called an apostle, because I persecuted the church of God. (I Corinthians 15:1-9)
