I do not like the term Irresistible Grace though I understand where and why the term originated. Some of Arminian persuasion use this term to imply that God must drag the elect "kicking and screaming" to Salvation, which is untrue. That being said Jesus Christ tells us in the Gospel according to John: John 6:37. All that the Father giveth me shall come to me; and him that cometh to me I will in no wise cast out. All that God the Father elects unto Salvation and gives to the Incarnate Son, Jesus Christ, shall come to Jesus Christ for Salvation. Other Scripture tell us that no one can come to Jesus Christ of his own volition. John 6:65. And he said, Therefore said I unto you, that no man can come unto me, except it were given unto him of my Father. John 6:44. No man can come to me, except the Father which hath sent me draw him: and I will raise him up at the last day.
