What is the bible verse about it being bad to turn children against God/faith?

i don't know if this is what you were talking about but here is one

Colossians 3:21

Fathers, do not provoke your children, lest they become discouraged

It's talking about discouraging them in the faith.

Read Deuteronomy 6:4-9.

Mat 18:5 And whoso shall receive one such little child in my name receiveth me.

Mat 18:6 But whoso shall offend one of these little ones which believe in me, it were better for him that a millstone were hanged about his neck, and that he were drowned in the depth of the sea.

Mat 18:7 Woe unto the world because of offences! for it must needs be that offences come; but woe to that man by whom the offence cometh!
