Are we born sinful?
The short answer
Yes, in the Bible's teaching people are born with a fallen nature inherited from Adam, inclined away from God before they choose any particular act. Christians have explained the details differently, but the texts point to a need that begins at birth, which is why salvation is presented as new birth, not self improvement.
The fuller answer
Pelagius, a British monk teaching in the early fifth century, should be stated fairly first. He taught that people are born morally neutral, able to choose good or evil, and that Adam's fall harmed others mainly by setting a bad example. He wanted to protect human responsibility and resist excuses for lazy living. Those concerns are understandable. The question is whether his account matches what David, Paul and the rest of Scripture say about the human heart from the very beginning of life.
Surely I was brought forth in iniquity; I was sinful when my mother conceived me.
Psalm 51:5 (BSB)
David, confessing serious adult sin, traces his problem deeper than one bad decision. He speaks of sinfulness reaching back to his birth and conception. Poetry should not be pressed like a laboratory report, yet his direction is plain: he does not see himself as a neutral person corrupted only by example. Paul gives the fuller argument in Romans chapter 5. Through one man, Adam, sin entered the world, and death came to all, with humanity counted in Adam as its first head.
Therefore, just as sin entered the world through one man, and death through sin, so also death was passed on to all men, because all sinned.
Romans 5:12 (BSB)
Augustine answered Pelagius from those texts in his anti-Pelagian works, including his writings on nature and grace and on original sin. He argued that Adam's descendants inherit both guilt and a disordered love: a nature bent toward self and away from God, so that even our choices are made by a heart already needing grace. Later churches have phrased the inheritance in different ways, and not all accept every part of Augustine's account. Few, reading Paul whole, settle for example alone.
All of us also lived among them at one time, fulfilling the cravings of our flesh and indulging its desires and thoughts. Like the rest, we were by nature children of wrath.
Ephesians 2:3 (BSB)
Paul describes people before Christ as by nature deserving wrath, following cravings rather than merely copying neighbours. This is not a claim that babies commit deliberate acts, nor that every person is as bad as they could possibly be. It is a claim about direction and need. A child needs rescue before she can ask for it. That is precisely why the gospel speaks of being born again: God must give new life, not simply wait for the old life to improve itself.
