Theologians call it the doctrine of “irresistible grace.”
“…those whom he called he also justified…” (Rom 8:30)
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 (which is made to all without distinction) can be, and often is, rejected; whereas the internal call (which is made only to the elect) cannot be rejected. It always results in conversion. By means of this special effectual call, the Spirit irresistibly draws sinners to Christ. He is not limited in His work of applying salvation by man’s will, nor is He dependent upon man’s cooperation for success. The Spirit graciously causes the elect sinner to cooperate, to believe, to repent, to come freely and willingly to Christ. (Matt 22:14; 23:37-39; John 1:12-13; 3:1-8; 3:16; 6:44; Rom 8:28-30; Eph 2:1-6)
While every true child of God may not be able to articulate this in words, he intuitively knows that we love Him only because He first loved us.
