: Palingenesis means “new birth” or “renewal,” but it has been misused throughout history to promote false ideas such as evolutionary development and reincarnation. Biblically, palingenesis refers instead to the true regeneration God brings through Jesus Christ.
The word palingenesis comes from Greek roots meaning “again” and “birth.” In the nineteenth century, it was used in evolutionary biology to describe the false idea that human embryos pass through earlier animal stages before birth, beginning as a fish, then an amphibian, a reptile, a bird, and finally a mammal. Ernst Haeckel’s drawings popularized this theory in schools, but later research exposed them as inaccurate, and the concept was rejected.
Outside of science, palingenesis has also been used in philosophy and religion to describe rebirth or renewal. In Eastern religions like Hinduism, it refers to reincarnation—the repeated cycle of death and rebirth. Politically or culturally, it has been used to describe a nation or movement “rising from the ashes” after collapse.
In the New Testament, the Greek word palingenesia appears twice: in Matthew 19:28, where Jesus speaks of the coming renewal of the world, and in Titus 3:5, where Paul uses it to describe the cleansing process of salvation. Elsewhere, related terms such as “born again” (John 3:3) and “born anew” (1 Peter 1:3, 23) describe the same divine work. In each case, Scripture presents new birth as a once-for-all act of God’s grace which brings a real and lasting transformation through Christ.
In Shakespeare’s Macbeth, Lady Macbeth is so troubled by the murder she conspired to carry out, that she regularly sleepwalks, washing her hands to rid them of the imaginary spot of blood from her victim. The spot never disappears, though, because it is psychological and spiritual rather than physical. Every human being has a similar spiritual spot called sin, and no amount of effort on our part can remove it. But through Jesus, God does what no one else can—washes away sin and gives a new heart that desires righteousness. When Paul wrote about the “washing of regeneration and renewal of the Holy Spirit” (Titus 3:5), he was describing how salvation is more than forgiveness. It is an inward transformation in which the Holy Spirit makes a person alive to God, changing their nature from the inside out.
Recognizing this truth helps believers to live with contentment even amid the sinfulness, chaos, and suffering in this world. That’s because our salvation is not in our fallible hands but is the result of the work Christ has already done on the cross. May others look toward us, see “the peace of God, which surpasses all understanding” (Philippians 4:7), and ask us how to get it.
