There are many, but I have seen two types of “Christianity” for several years.
One is based on feelings. Baptists have been know for this. Their worship and preaching are designed to make you feel good about yourself. The technical details of the truth found in scripture are minimized for the sake of unity. This method has found its way into many other groups including the church of Christ. Children from this side are easy to control and harm with false doctrine.
The other group is only the known facts are important. They are strict without love. Love is minimized for the sake of what they see as the truth. They fear love will weaken the following of the Law. It does not have to. Children from this side often grow up and abandon Christianity as controlling and harmful.
Both are extreme views. Neither is correct today as all of it has been influenced by the world. If you have been under either, the point to remember is that the basics of Christian truth are valid and necessary for a good life. All of God’s Law is built on Love. True Christian principles with love are the most important thing you can pass on to your children. At the same time one must realize that you only teach. You can not force children to believe or act on your teaching on their own. Scripture is true. If you teach with a good balance of love they will come back to it.
Proverbs 22:6 “Train up a child in the way he should go: and when he is old, he will not depart from it.”
