A Sermon About Faith in the Truth of Jesus
Acts 3:13-16
"The God of Abraham, the God of Isaac, and the God of Jacob, the God of our fathers, glorified his servant Jesus, whom you delivered over and denied in the presence of Pilate, when he had decided to release him. But you denied the Holy and Righteous One, and asked for a murderer to be granted to you, and you killed the Author of life, whom God raised from the dead. To this we are witnesses. And his name; by faith in his name, has made this man strong whom you see and know, and the faith that is through Jesus has given the man this perfect health in the presence of you all."
What if what they believed about Jesus is not true? What if He's not the Son of God? And in the light of all they've witnessed and the joy of their faith, everything they believed is based upon a false premise. What have they lost believing what they believe?
They're filled with joy, so much existential joy and peace in Christ's name. They're witnessing miracles in His name and the people are astonished. This faith brought them joy, purpose, and a sense of divine connection, even amidst persecution. But what if it's not true? What have they lost?
Even if their beliefs were untrue, the believers’ experiences weren’t without value. Their faith gave them a sense of purpose, community, and hope in a world often marked by suffering and uncertainty. Faith in Jesus shaped the early believers’ ethics; love, forgiveness, and service to others. These values likely led to positive actions, such as caring for the poor or building supportive communities. The subjective power of belief can sometimes produce real-world effects, like improved health outcomes, as seen in studies on the placebo effect. Their faith created a tight-knit community bound by shared purpose. This sense of belonging is a profound human need, and the early Christians found it in their devotion to Jesus. If their faith was based on a false premise, the "loss" depends on what they valued most and what alternatives existed.
This is how the world sees things, how a rationalist views matters of faith. This scenario echoes Pascal’s Wager, a philosophical argument by Blaise Pascal. He suggested that believing in God (or, by extension, Jesus) is a rational "bet" because the potential gains (eternal life, joy, meaning) outweigh the losses (sacrifices, skepticism) if God exists. If God doesn’t exist, the believer still gains a meaningful life, while the skeptic gains little beyond intellectual correctness.
However, critics of this view (for instance existentialists like Sartre) might argue that living inauthentically; clinging to a false belief, undermines human freedom and integrity. The loss, then, would be the opportunity to face reality courageously, without the crutch of a comforting myth.
But what if it was true? What if what they witnessed and their faith in the name of Jesus Christ is true?
Take another look at what Peter was preaching in our focus scripture (Acts 3:13-16):
When Peter walked into that temple and saw that lame man, God gave him faith. And it was the name of Jesus Christ that healed that man. And 5000 people who had previously shouted "crucify him!" at the cross of Jesus were given this gift of faith. God did that. That's what Peter said. The power of faith that is a gift from God did that. If Jesus is indeed the Son of God, the "Holy and Righteous One," the "Author of life" raised from the dead, as Peter proclaims, what does this mean for the early believers and their experiences of joy, miracles, and purpose?
The implications are transformative, not only for their immediate experiences but for their eternal destiny and the meaning of their lives. If Jesus is the Son of God, His resurrection validates His claims to be the way to eternal life (John 14:6). Then their joy and peace in this life are not just psychological but a foretaste of eternal communion with God. This is the ultimate gain, far surpassing temporal benefits like community or purpose.
The truth is the believers’ sense of purpose wasn’t just a subjective feeling but a response to a divine reality. Their faith in Jesus as the Messiah gave them a mission to spread the gospel, as seen in their bold witness despite persecution. The tight-knit community they built was not just a human construct but the early manifestation of the Church, the body of Christ, empowered by the Holy Spirit. Their sense of belonging was grounded in a divine reality, not merely a shared delusion.
Their faith enabled them to participate in God’s work, as Jesus promised (John 14:12: "Whoever believes in me will do the works I have been doing" ). Their persecution and sacrifices were investments in eternal rewards (Matthew 5:11-12: "Blessed are you when people insult you…great is your reward in heaven" ). Their suffering had purpose, contributing to God’s redemptive plan. Unlike the rationalist’s fear of delusion, their faith was grounded in the truth of God’s revelation, as confirmed by Jesus’ resurrection and the miracles they witnessed. Their devotion to Jesus was the "narrow road" to life (Matthew 7:14), not a detour from a better option. They understood in their faith that other paths (e.g., paganism, philosophy, or self-interest) would have led them away from God’s truth. And besides, their faith was rational not because of a wager but because it was confirmed by divine acts, like the resurrection and the healing in Acts 3.
Pascal’s framework underestimates the transformative power of true faith. Sartre might argue that clinging to faith, if false, undermines authentic existence by avoiding the courage to face a meaningless universe, but f Jesus is the Son of God, the believers’ faith was the most authentic choice possible; it aligned them with the ultimate meaning of existence: communion with God. Far from a "crutch," their faith required courage to face persecution and proclaim a countercultural message. Their joy and purpose weren’t escapes from reality but reflections of the deepest reality.
True freedom, in Christian theology, comes from surrendering to God’s truth (John 8:32: "You will know the truth, and the truth will set you free" ). The believers’ devotion to Jesus liberated them from their sin and despair, it did not constrain them. It gave them hope in Christ's return. The believers lost nothing and gained everything; eternal life, divine purpose, and the joy of knowing God. Their lives were not just enriched but redeemed, with eternal significance.
Peter didn't just drop this truth bomb, mic-drop and walk off...
Acts 3:17-21
"And now, brothers, I know that you acted in ignorance, as did also your rulers. But what God foretold by the mouth of all the prophets, that his Christ would suffer, he thus fulfilled. Repent therefore, and turn back, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for restoring all the things about which God spoke by the mouth of his holy prophets long ago."
He builds on the truth he’s laid out, showing compassion, offering hope, and calling the crowd to action. Peter isn’t just preaching theology; he’s inviting the crowd into a transformed life based on the truth of Jesus as the Messiah. If Jesus is the Son of God, this shows the depth of God’s mercy. The crowd, complicit in Jesus’ crucifixion, isn’t condemned outright but offered a chance to repent. Peter’s call to repent means they, too, can share in the believers’ joy and purpose. If Jesus is the Messiah, their ignorance doesn’t disqualify them; they can join the community of faith, experiencing the same divine connection. If Jesus is the Son of God, repentance is the gateway to a transformed life. If their faith is true, their joy is not just emotional but a sign of God’s presence, as promised in the "times of refreshing" (v. 19). Faith becomes a spiritual renewal in this life and the ultimate restoration when Jesus returns.
They’ve gained forgiveness, a role in God’s plan, and the hope of eternal restoration. Their faith is a courageous embrace of reality, confirmed by prophecy, miracles, and the promise of "times of refreshing." There is no loss, only infinite gain.
Prayer:
Heavenly Father, God of Abraham, Isaac, and Jacob,
You glorified Your servant Jesus, the Holy and Righteous One, the Author of life, raised from the dead. We stand in awe of Your power, revealed through the miracles worked in His name and the faith that makes us whole.
Lord, we come before You seeking the truth of Jesus, Your Son. If He is indeed the Messiah, as Peter proclaimed, let our hearts be anchored in that reality. Fill us with the joy and peace that come from knowing Him, not as a fleeting hope, but as the eternal truth that transforms our lives.
Forgive us, as You forgave those who acted in ignorance.
We thank You for the faith, and divine connection in Jesus’ name.
If we doubt, Lord, strengthen us with the evidence of Your works. Send your Spirit to instruct our hearts.
Lord Jesus, You are the way, the truth, and the life. May our lives reflect Your glory, our hearts embrace Your purpose, and our faith shine as a witness to Your redeeming love. We await Your return with hope, trusting in the promise of restoration.
In Your holy and precious name, we pray,
Amen.
