Here is why many sincere people, including children of religious leaders, are falling away. They are impatient. What are they impatient about? The things that Jesus taught that the church doesn't teach about.
For example, Jesus says in Matthew 7:7,8:
7“Ask and it will be given to you; seek and you will find; knock and the door will be opened to you. 8For everyone who asks receives; the one who seeks finds; and to the one who knocks, the door will be opened.
Yet, how many times do we ask and NOT receive? Why? After all, if it was not God's will for us to receive it, Jesus wouldn't have said it.
The structure of the universe must be maintained. When Jesus was tempted in the wilderness after He had fasted for 40 days and was very hungry, the Tempter said, "If you are the Son of God, command that these stones be made into bread." Jesus answered, "Man does not live by bread alone, but by every word that comes out of the mouth of God." In other words, asking and receiving must come through every word that God has brought into existence throughout the operation - physics - of the universe.
St. Paul says in 2 Corinthians chapter 4:
6For God, who said, “Let light shine out of darkness,” made his light shine in our hearts to give us the light of the knowledge of God’s glory displayed in the face of Christ.
7But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us.
In other words, we have the treasure of the power of God that brings us to salvation, and can bring us into all kinds of powerful and wonderful things, NOT because we are being denied these things in our jars of clay (our bodies), but to show that the power is from God and not from us. After all, look at how powerful our bodies are; nobody knows how they work they are so full of the knowledge that God has placed in them.
St. Paul goes on to say:
12So then, death is at work in us, but life is at work in you.
Death was at work in the Gospel preachers, because they were bypassing all kinds of powerful things that they could do and be, just to bring the message of the Gospel of Life - Jesus salvation - to the people.
Since everything operates through every word of God (the physics of the universe), and since every power is given through the grace that Jesus provides through His work on the cross, why don't the churches have a training program to bring people into the use of the power of God that Jesus won for them... the power of, "Ask and it will be given to you," etc.?
The children of Christian leaders are simply impatient and frustrated by their parents, the leaders. They are being told by Scripture that if they have faith they can move mountains, and nothing will be impossible for them. But nobody has a training course for them to use to get to the point of having a little more faith... to do some of these great and wondrous things. Rather, the church leaders keep on rebuilding the foundation of Jesus-salvation, often tearing it down somewhat to rebuild it again, instead of building on it, this Jesus-salvation foundation, the buildings of power.
Meanwhile wicked people use the faith they have from God - even though they don't really know where it is from - to build all kinds of fantastic and powerful things in this world... some of which produce great evil.
NOTE: The important thing is to maintain your personal salvation with Jesus, both before and after you start being built in the faith that you can use to move mountains.
