Are the mute condemned to hellfire frombeing unable to speak?
Are infants unable to be saved since they cannot confess or believe? Or are all infants saved by virtue of being born? (And then when do they become "unsaved" again so that they need to confess the Lord Jesus to become saved again?) Your post is quite confusing.
Have you thought that there are different ways to confess? Nobody could believe that God would expect someone to do something he is physically unable to do! But a mute person can walk to the front of the church and give witness that he has accepted Christ.

We believe that infants and children under the age of accountability are not expected to understand and believe. But as soon as they are old enough, our children are encouraged to make profession of faith. And before you ask about it, the age of accountability is not fixed, some children mature sooner than others. It is up to the parents and the pastor to recognize when a child is ready! As to what happens to children who die before reaching that age, they have not had a chance to sin. God would not condemn a child to hell because he hadn't had a chance to accept Him!
