The doctrine of election is not primarily the abstruse, difficult article of faith that most Christians – indeed, most theologians – are intimidated by (at best). Rather, in the Scriptures it is given as a source of confidence for the Christian, and a foundation of the Christian life.
… we must always take as one unit the entire doctrine of God’s purpose, counsel, will, and ordinance concerning our redemption, call, justification, and salvation, as Paul treats and explains this article (Rom. 8:28ff.; Eph. 1:4ff.) and as Christ likewise does in the parable (Matt. 20:2–14), namely, that in his purpose and counsel God had ordained the following:
1. That through Christ the human race has truly been redeemed and reconciled with God and that by his innocent obedience, suffering, and death Christ has earned for us “the righteousness which avails before God”2 and eternal life.
2. That this merit and these benefits of Christ are to be offered, given, and distributed to us through his Word and sacraments.
3. That he would be effective and active in us by his Holy Spirit through the Word when it is preached, heard, and meditated on, would convert hearts to true repentance, and would enlighten them in the true faith.
4. That he would justify and graciously accept into the adoption of children and into the inheritance of eternal life all who in sincere repentance and true faith accept Christ.
5. That he also would sanctify in love all who are thus justified, as St. Paul says (Eph. 1:4).
6. That he also would protect them in their great weakness against the devil, the world, and the flesh, guide and lead them in his ways, raise them up again when they stumble, and comfort and preserve them in tribulation and temptation.
7. That he would also strengthen and increase in them the good work which he has begun, and preserve them unto the end, if they cling to God’s Word, pray diligently, persevere in the grace of God, and use faithfully the gifts they have received.
8. That, finally, he would eternally save and glorify in eternal life those whom he has elected, called, and justified.
