What is the proper way of teaching the children about the church? (Part 1 of 2)

This is what I understand from this Brother Eli's video:

In order to bring the youngsters to the ministry, we have to open their minds first. Acts 26:18 admonishes us to open their eyes, and turn them from darkness to light, and from the power of Satan to God, so that they may be forgiven of their sins.

There's no need to challenge them rather, to open their eyes to the truth of the Bible. They have to be aware of the existence of God, as Eccl. 12:1 admonishes one to remember his Creator in the days of his youth. This is more so when the evil days come after the youth period, one shall not say he has no pleasure in serving God.

When we start early to learn the pleasure of serving God, like Brother Eli as an example, that will lead us to the later age.
