Grace undergirds

(1) the doctrine of election to life. Paul wrote concerning the core of believing Jews, “there is a remnant chosen by grace” (kat eklogen charitos, Rom 11:5; cf. Eph 1:4–6).

(2) The doctrine of effectual calling. Concerning his life-transforming encounter with Christ near Damascus, the apostle wrote, “God … called me by his grace” (Gal 1:15).

(3) The doctrine of faith. Luke described disciples in Achaia as “those who by grace had believed” (Acts 18:27).

(4) The forgiveness of sins. Here we cite the words of Paul: “In him we have … the forgiveness of sins, in accordance with the riches of God’s grace that he lavished on us with all wisdom and understanding” (Eph 1:7–8).

(5) The doctrine of justification. Paul wrote that saints “are justified freely by his grace through the redemption that came by Jesus Christ” (Rom 3:24; cf. Tit 3:7).

(6) The doctrine of regeneration. Peter wrote concerning the heavenly Father, “In his great mercy [eleos] he has given us new birth” (1 Pet 1:3).

(7) The doctrine of sanctification. Grace delivers believers from the dominion of sin and enables them to become experientially holy. Thus Peter commanded Christians to “grow in the grace and knowledge of our Lord and Savior Jesus Christ” (2 Pet 3:18; cf. Rom 6:11–23).

(8) The reality of giftedness spiritually. In the words of Paul, “we have different gifts [charismata], according to the grace given us” (Rom 12:6; cf. Eph 4:7).

(9) The victorious Christian life. Hear Christ’s words to Paul concerning his persistent illness: “My grace is sufficient for you, for my power is made perfect in weakness” (2 Cor 12:9).

(10) The doctrine of perseverance or the preservation of the saints. Paul enjoined Timothy to “be strong in the grace that is in Christ Jesus” (2 Tim 2:1; cf. v. 3). Finally,

(11) grace relates to the doctrine of eternal life. As expressed by Paul, “grace increased all the more, so that … grace might reign through righteousness to bring eternal life through Jesus Christ our Lord” (Rom 5:21; cf. v. 17). So pertinent is grace to each aspect of the plan of salvation that the great Spurgeon could write, “We see a golden thread of grace moving through the whole of the Christian’s history, from his election before all worlds, even to his admission to the heavenly rest.”
