What is the proper way to teach children about church

We do not challenge children, we have to open their mind first

* Acts 26:18  To open their eyes, and to turn them from darkness to light, and from the power of Satan unto God, that they may receive forgiveness of sins, and inheritance among them which are sanctified by faith that is in me.

Let them see reality about what the Bible says and reality surrounding them, let them know that best time to serve God is when they are young

* Ecclesiastes 12:1  Remember now thy Creator in the days of thy youth, while the evil days come not, nor the years draw nigh, when thou shalt say, I have no pleasure in them;

Do not wait for that Day BiBle call evil 😈 day before you start serving God, in the later age,  man would not have the pleasure of serving God
