Whosoever calls on the name of the Lord will be saved. Anyone not called will have no interest in calling on the name of the Lord.
Romans 8:28 And we know that all things work together for good to them that love God, to them who are the called according to his purpose.
29 For whom he did foreknow, he also did predestinate to be conformed to the image of his Son, that he might be the firstborn among many brethren.
30 Moreover whom he did predestinate, them he also called: and whom he called, them he also justified: and whom he justified, them he also glorified.
God does the calling on the heart he has changed.
Jeremiah 31:31 Behold the days come, saith the Lord, that I will make a new covenant with the house of Israel, and with the house of Judah:
32 Not according to the covenant that I made with their fathers in the day I took them by the hand to bring them out of the land of Egypt; which my covenant they brake, although I was a husband unto them, saith the Lord:
33 But this shall be the covenant that I will make with the house of Israel; after those days saith the Lord, I will put my laws in their inward parts, and write it in their hearts; and I will be their God and they shall be my people.
34 And they shall teach no more every man his neighbor, and every man his brother, saying, know the Lord: for they shall all know me from the least of them to the greatest of them: for I will forgive their iniquity, and I will remember their sin no more.
