Age of accountability,Objections
<p>Critics point out that nowhere does the Bible spell out any age of accountability. Thus, it is purely speculative. In response, it is noteworthy that there is some evidence in Scripture that there is some point of moral responsibility in one's life. In addition, both experience and common consent inform us that tiny children are not morally responsible. This is why small children do not stand trial for wrongs they do. Psychologically, when they are infants and small children, their rational faculties have not even developed to discern good from evil. Finally, the fact that it is difficult to point to a precise age at which this occurs is not an insurmountable problem. Like self-consciousness, even if we do not know precisely when it occurs, we know that it occurs. In fact, the precise age of accountability may differ individually, depending on their moral development. Perhaps it is earlier for those who are exposed to concepts of moral right and wrong earlier. At any rate, it probably occurs sometime between ages four and twelve. The point at which it occurs is when the individual is old enough to understand the difference between moral right and wrong and the consequences of making moral choices. In biblical terms, when they are aware of the "law written in their hearts" (<a href="http://www.crossbooks.com/verse.asp?ref=Ro+2%3A15">Rom. 2:15</a>). They are morally accountable when they are old enough to know that what they do is against the moral law of God. Or, as Isaiah said, they are morally responsible when they are old enough to "to reject the wrong and choose the right" (<a href="http://www.crossbooks.com/verse.asp?ref=Isa+7%3A15">Isa. 7:15</a>).
