Arminianism: The Holy Spirit Can Be Effectually Resisted - The Spirit calls inwardly all those who are called outwardly by the gospel invitation; He does all that He can to bring every sinner to salvation. But inasmuch as man is free, he can successfully resist the Spirit's call. The Spirit cannot regenerate the sinner until he believes; faith (which is man's contribution) proceeds and makes possible the new birth. Thus, man's free will limits the Spirit in the application of Christ's saving work. The Holy Spirit can only draw to Christ those who allow Him to have His way with them. Until the sinner responds, the Spirit cannot give life. God's grace, therefore, is not invincible; it can be, and often is, resisted and thwarted by man.

Reformed (Calvinism) :  - The Efficacious Call of the Spirit or Irresistible Grace -  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 internal call (which is 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 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. God's grace, therefore, is invincible; it never fails to result in the salvation of those to whom it is extended.
