While the status of infants and those who never reach moral competence is a difficult question, it appears that our Lord did not regard them as under condemnation. Indeed, he held them up as an example of the type of person who will inherit the kingdom of God (Matt. 18:3; 19:14). David had confidence that he would again see his child who had died (2 Sam. 12:23). On the basis of such considerations, it is difficult to maintain that children are to be thought of as sinful, condemned, and lost.”
