Did Paul of himself all of a sudden become a believer or did Jesus call Paul and make a believer of him for the purpose of God? Acts 9:15,16 But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel: For I will shew him how great things he must suffer for my name's sake. 1 Tim 1:12-16 And I thank Christ Jesus our Lord, who hath enabled me, for that he counted me faithful, putting me into the ministry; Who was before a blasphemer, and a persecutor, and injurious: but I obtained mercy, because I did ignorantly in unbelief. And the grace of our Lord was exceeding abundant with faith and love (shed abroad by the Holy Spirit), which is in Christ Jesus. This a faithful saying, and worthy of all acceptation, that Christ Jesus came into the world to save sinners; of whom I am chief. Howbeit for this cause I obtained mercy, that in me first Jesus Christ might shew forth all longsuffering, for a pattern to them which should hereafter believe on him to life everlasting. John 10:26-28 But ye believe not, because ye are not of my sheep, as I said unto you. My sheep hear my voice, and I know them, and they follow me: And I give unto them eternal life; and they shall never perish, neither shall any pluck them out of my hand.
