The Bible never says that we are born sinners. We become sinners by sinning. The Bible does say that by the choice of one man, Adam, sin entered into the world, and death by sin, for all have sinned (Romans:5:12). Adam’s sin separated him from God, the Source of life, and his body began to die. As a result, all of his descendants inherited bodies subject to death—but they can’t blame Adam, because they, too, have sinned.
"For there is not a just man upon earth, that doeth good, and sinneth not."
