As I stated, using "hard cases", such as dying on the way to baptism, does NOT negate clear teaching of the New Testament. Acts 2:38 does not say that baptism illustrates belief, it says that baptism is for the remission of sins.
Please don't take this as shouting but one of the bizarre ritual around here seem to be thinking God works in all sorts of different ways in all sorts of different circumstances to save individuals. God has special ways in saving children, saving people on desert islands, saving people in the Old Testaments and now making special exceptions when they're not baptized although, you say, it's required. Quite frankly I grow dizzy trying to keep straight the salvation methods of the Arminians.
If God does it for one, He does it for all. This includes those who are baptized and those who are not. God is consistent in His salvation plan and method. God shows no partiality.
