Bird,
Indeed, all young children are lovable and have no prejudices, but because of inherited sin, none are really innocent. Consider how David, and man after God's own heart, stated this concept, Ps 51:5, Rom 5:12, 3:23. All need the Great Ransom Sacrifice that Jesus, The Lamb of God, provided, John 1:29, Matt 20:28, Gal 2:16.
According to the Holy Scriptures a child will receive the same reward as their parents, until he has reached an age of responsibility, that is why a person must learn about God and then teach his children, Deut 6:4-9, 30:19,20, Eph 6:4.
It is very interesting the way you put your statement about young children. Jesus stated that no one would enter The Kingdom of God unless he became like a little child, Matt 18:2-6.
There are people like that today!! They belong to the ONE religion that Paul mentioned at Eph 4:3-6. The problem that people have identifying that religion is: they believe that the one true religion would be loved and accepted. The opposite is true, they will be hated by every nation on earth, Matt 24:9, they would be looked down on and persecuted, 1Cor 1:26-30, 1Tim 3:12, Luke 6:22,23. They would not be a friend of the world, John 15:18-20, James 4:4, 1John 2:15-17. You can identify them by the love they show, John 13:34,35.
