Salvation is accomplished by the almighty power of the Triune God. The Father chose a people, the Son died for them, the Holy Spirit makes Christ's death effective by bringing the elect to faith and repentance, thereby causing them to willingly obey the gospel. The entire process (election, redemption, regeneration) is the work of God and is by grace alone. Thus God, not man, determines who will be the recipients of the gift of salvation.

Quotes from the same author

Although the sovereignty of God is universal and absolute, it is not the sovereignty of blind power. It is coupled with infinite wisdom, holiness and love. And this doctrine, when properly understood, is a most comforting and reassuring one. Who would not prefer to have his affairs in the hands of a God of infinite power, wisdom, holiness and love, rather than to have them left to fate, or chance, or irrevocable natural law, or to short-sighted and perverted self? Those who reject God's sovereignty should consider what alternatives they have left.

A man is not saved because he believes in Christ, he believes in Christ because he is saved.
 Loraine Boettner
If it be objected that God must give every man an opportunity to be saved, we reply that the outward call does give every man who hears it an opportunity to be saved. The message is: 'Believe on the Lord Jesus Christ and thou shalt be saved.'
