Crowcamp asked "Really, my question comes more from the other passage offered in the OP. How do we come to Jesus? He says that is only by the will of the Father. "
Once this is answered in truth the way Jesus would answer it for you then you begin to understand more about this topic.
How Does God call his people.
1 Paul, a servant of Jesus Christ, called to be an apostle, separated unto the gospel of God, 2 (Which he had promised afore by his prophets in the holy scriptures,) 3 Concerning his Son Jesus Christ our Lord, which was made of the seed of David according to the flesh; 4 And declared F1 to be the Son of God with power, according to the spirit of holiness, by the resurrection from the dead: 5 By whom we have received grace and apostleship, for obedience F2 to the faith among all nations, for his name: 6 Among whom are ye also the called of Jesus Christ: 7 To all that be in Rome, beloved of God, called to be saints: Grace to you and peace from God our Father, and the Lord Jesus Christ. Romans 1:1-7 (KJV)
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. Romans 1:16 (KJV)
13 For whosoever shall call upon the name of the Lord shall be saved. 14 How then shall they call on him in whom they have not believed? and how shall they believe in him of whom they have not heard? and how shall they hear without a preacher? 15 And how shall they preach, except they be sent? as it is written, How beautiful are the feet of them that preach the gospel of peace, and bring glad tidings of good things! 16 But they have not all obeyed the gospel. For Esaias saith, Lord, who hath believed our report F39? 17 So then faith cometh by hearing, and hearing by the word of God. Romans 10:13-17 (KJV)
