How Does the Holy Spirit Bring Me to Faith?

Luther’s explanation of the Third Article contains what may be the single most important sentence in the Small Catechism for understanding the Lutheran faith. Confessing “I believe in the Holy Spirit,” he begins: “I believe that I cannot by my own reason or strength believe in Jesus Christ, my Lord, or come to Him.”

Sit with how radical that is. Luther does not say faith is hard to produce, or that we need the Spirit’s help to believe. He says we cannot believe by our own reason or strength at all. Coming to Christ is not something we manage even partly on our own; by nature we are spiritually dead and blind, unable to choose or generate faith. Jesus said it plainly: “No one can come to me unless the Father… draws him” (John 6:44); “no one can say ‘Jesus is Lord’ except in the Holy Spirit” (1 Corinthians 12:3). This demolishes every version of “I found God” or “I decided to believe” as the ultimate account. Left to ourselves, we would never come.

So how does anyone come to faith? Luther continues: “but the Holy Spirit has called me by the Gospel, enlightened me with His gifts, sanctified and kept me in the true faith.” He did it—the Spirit, working through the Gospel. Faith is entirely his gift and his doing, from first to last: he calls, enlightens, sanctifies, and keeps. Even your continuing to believe tomorrow is his work, not your grip. “By grace you have been saved through faith. And this is not your own doing; it is the gift of God” (Ephesians 2:8).

This is the deepest comfort in all of Lutheran theology, and it is worth grasping tightly. If your faith were finally your own achievement—your decision, your sincerity, your spiritual effort—then your salvation would be only as secure as your own wavering heart, and you would have every reason to be anxious. But if the Holy Spirit called you, keeps you, and will “on the Last Day raise me and all the dead, and give eternal life to me and all believers in Christ,” then your salvation rests on God’s faithfulness, not yours. You did not begin this by your strength; you will not be kept in it by your strength either. The One who brought you to faith holds you there—and “this is most certainly true.”
