If you do not see Gods Grace in your own salvation I can never explain to you the grace of God in the salvation of a child!
Yes, you can. Again, correlate the command "Repent, and be baptized!" with the salvation of an infant. Why are infants, who you say are born sinners, elected to heaven?
BTW--the reason there are so many I's in my method is the "Repent!" portion of that verse...
