So between my child and God there is a tremendous gap. He or she is estranged from God. No matter how gorgeous the child is there is a tremendous gulf between God and that child, and that gulf is sin. A child s bent towards evil begins to manifest itself very, very quickly, says the Psalmist. In this case, lying manifests itself from the earliest of days.
Children sin because they are sinners.
J.C. Ryle says, Remember, children are born with a decided bias toward evil. And therefore if you let them choose for themselves they are certain to choose wrong. It is natural for us to do wrong. Foolishness is bound up in the heart of a child. A child left to himself will bring his mother to shame.
