Age of accountability
<p>As to the age of accountability, Isaiah spoke of a little child before "he knows enough to reject the wrong and choose the right" (<a href="http://www.crossbooks.com/verse.asp?ref=Isa+7%3A15">Isa. 7:15</a>). This seems to imply that there is an age of moral accountability. Jesus said even of adults, "If you were blind, you would not be guilty of sin; but now that you claim you can see, your guilt remains" (<a href="http://www.crossbooks.com/verse.asp?ref=Jn+9%3A41">John 9:41</a>). </p>
<p>
In response, critics observe that even if this referred to an age of accountability, it would not thereby prove all infants are saved. For there are still at least two other issues that must be settled before one can prove this, namely, </p>
<ol>
<li>that inherited depravity in itself is not enough to send one to hell and </li>
<li>that faith is not an absolute essential to salvation. </li>
</ol>
<p>In short, Isaiah's reference to a young child not yet knowing good and evil may refer only to personal or social guilt, not to inherited sin.</p>
