All through the ages, it has always been easier to teach a child about the Ways and Wonders of the Lord than an adult. This is the way the Lord intended it (see Proverbs 22:6 "Train up a child in the way he should go; even when he is old he will not depart from it.) We all know this from our days either in Sunday school. Many of us, including my wife and myself, have taught or are still in children's ministry. Their joy and wonder and innocence about God are still putting hardened young people and adults to shame!
As Ken Ham and Britt Beamer's research discovered a few years ago, in the book Already Gone, by the time these same kids get to 6th grade and up, we lose them to the world! Not all, of course, but the majority who make up our youth groups. The current corrupt American culture and education systems have succeeded in training up our kids in the way they should NOT go and God will punish those people...and our children if we do not try to teach them as Jesus instructed Nicodemus here in John chapter 3.
The term He used in John 3:3 is mind boggling and puts a lie to religion by works, period. Most Christians have no clue what "born again" really means. The actual MEANING of the words Jesus used are "gennao" and "anóthen". This literally means that "unless I (Jesus) brings you forth ANEW from Heaven MYSELF you are not a child of the Kingdom of Heaven"!!!!! THINK ABOUT THIS FOR A LONG TIME TODAY!
Does this describe you? Has Jesus Himself literally come down into your inner person and made you new, a new creation, by birthing your soul, as a new child into His Kingdom? Please examine yourself today and see if ye be in the Faith. Your future residence depends on it. Amen
