Train up a child . . .
-Those children who are of sufficient years to sin and be saved by faith have to listen to the gospel and receive it by faith. And they can do this, God the Holy Spirit helping them. There is no doubt about it, because great numbers have done it. I will not say at what age children are first capable of receiving the knowledge of Christ, but it is much earlier than some fancy. CHARLES SPURGEON
Prov 22:6 Train up a child in the way he should go: and when he is old, he will not depart from it.
Deut 6:6-7 These commandments that I give you today are to be on your hearts. Impress them on your children. Talk about them when you sit at home and when you walk along the road, when you lie down and when you get up.
Ps 78:4 We will not hide them from their descendants; we will tell the next generation the praiseworthy deeds of the Lord, his power, and the wonders he has done.
