Do you know how a worm gets inside an apple? Maybe you think the worm burrows in from the outside. No, scientists have discovered that the worm comes from inside. But how does he get in there? Simple! An insect lays an egg in the apple blossom. Sometime later, the worm hatches right in the heart of the apple and then it eats his way out. Sin is a bit like that: it is already in our hearts before we are even born; sin is passed on in our genes, from mother to child right the way back to Adam and Eve.
