Summary

Faith: Gift, Not Decision

Faith is not something the human heart manufactures. By nature, "the mind that is set on the flesh is hostile to God. It does not submit to God's law; indeed, it cannot" Romans 8:7. Apart from the Spirit, no one can even confess that Jesus is Lord 1 Corinthians 12:3. Scripture is unambiguous: "By grace you have been saved through faith. And this is not your own doing; it is the gift of God, not a result of works" Ephesians 2:8-9. Jesus Himself says, "You did not choose me, but I chose you" John 15:16.

This is why the Lutheran Church speaks the gospel in the language of because/therefore rather than if/then. The law says, "If you do this, then God will accept you." The gospel says, "Because Christ has died and risen, therefore you are forgiven and belong to Him." When faith is preached as a decision we make, the gospel quietly turns back into law—one more work to perform, with the lingering question of whether we performed it sincerely enough. Augustine compared faith to falling in love: not a willed decision struck on a particular day, but the awakening of a heart God has changed. See Joshua: Servant of the Lord - Lesson 9 for a fuller treatment of how Joshua's "choose this day whom you will serve" must be read alongside Jesus' word that He chose us first.

Weak Faith Is Saving Faith

A weak faith is still a saving faith. The desperate father in the Gospel cried, "I believe; help my unbelief!" Mark 9:24, and Jesus did not turn him away. Christ promises, "Whoever comes to me I will never cast out" John 6:37. The very words of the Supper, "given and shed for you for the forgiveness of sins," are spoken to weak and struggling sinners precisely so that we would be drawn to Him and strengthened. The struggling believer who comes confessing sin is not the unworthy communicant; the unrepentant—the "sorry, not sorry" heart—is. As Confession: Repentance and Forgiveness - Lesson 4 puts it, what makes one worthy to receive Christ's body and blood is not the quantity of one's faith but trust in His words.

Faith Receives, Then Lives

Faith receives Christ's finished work, and from that reception it lives. We do not need to manufacture certainty by introspection; we look outside ourselves to what God has done. In baptism, God made His decision about us—He called us His own, and nothing snatches us from His hand. From that secure place, faith does what faith does: it confesses sin honestly, it receives absolution as the very voice of Christ, and it loves the neighbor God has placed before us.

Faith is also nourished. It is fed by Word and Sacrament, strengthened in prayer, and held up in fellowship with brothers and sisters. As Confession: Repentance and Forgiveness - Lesson 4 reminds us, no Christian is an island. The Spirit who gave us faith uses these means to keep us in it.

Faith Looks Outward to Christ

When Satan whispers and we are tempted to measure faith by our feelings, the answer is never "try harder to believe." That is like telling a drowning person to swim. The answer is the gospel. Christ has died for sinners; the tomb is empty; the Father has accepted the sacrifice; you are baptized; you are forgiven; you are His. Faith clings to that promise—not because faith is strong, but because the One it clings to is.

So we confess, with the whole Church: "By grace I have been saved through faith. And this is not my own doing; it is the gift of God."
