In addition to the outward general call to salvation which is made to everyone who hears the gospel, the Holy Spirit extends to the elect a special inward call that inevitably brings them to salvation. The external call (made without distinction) can be and is often rejected; whereas the internal call (made only to the elect) cannot be rejected; it always results in conversion. By means of this special call, the Spirit irresistibly draws sinners to Christ. He is not limited by man's will or dependent upon man's cooperation for success. The Spirit graciously causes the elect sinners to cooperate, to believe, to repent, and to come freely and willingly to Christ. God's grace, therefore, is invincible; it never fails to result in the salvation of those to whom it is extended.
