Election
Union between Christ and his people was planned already in eternity, in the sovereign pretemporal decision whereby God the Father selected certain sinners as His own. Christ himself was chosen to be our Savior before the creation of the world (1 Pet. 1:20); When the Father chose Christ, he also chose us (Ephesians 1:4). We are initially united with Christ in regeneration; next we appropriate and continue to live out of this union through faith. Third, we are justified in union with Christ. Fourth, we are sanctified through union with Christ. Fifth, we persevere in the life of faith in union with Christ. Finally, we shall be eternally glorified with Christ.
This pretemporal choice was not based on the fact that God knew which persons would believe of their own free will, for there is no person which fits that description. This decision was based upon God's sovereign good pleasure alone. It is God's gracious decision, from eternity past, to save fallen souls of His own choosing. Therefore, God will infallibly bring all of His elect to final perseverance and eternal life (Phil 1:6; John 10:29; Rom 8:30; John 6:37, 39). The Persons of the Trinity work in harmony to accomplish and apply salvation. The Father, from eternity, elects a particular people for Himself (Ephesians 1:4, 5; Rom 8:29, 30) Christ redeems those the Father has "given Him" (John 6:37, 39; 10:29) and the Holy Spirit likewise applies the redemptive benefits of the atonement to the same. (John 1:13; 6:63; James 1:18, 1 Peter 1:23,25).
