QUESTION: If infants are born in a state of justification, are they not also regenerated, since regeneration accompanies justification?
ANSWER: No. Justification is a legal term for forgiveness of sin and hence it cannot be properly applied to one who has never sinned and is incapable of sinning. Acceptance would be a better term. This does not imply the infant's regeneration. All infants belong to Christ, who redeemed them. It is not wise to apply to them the terms which belong only to believers, such as justification, regeneration and sanctification. Bishop Gilbert Haven, at my dinner table, asked the lady presiding whether the children were not born regenerate. Her reply was, "If they were, they all backslid before they were more than three weeks old."
