It is a sin against God not to pray for the Israel of God, especially for those of them that are under our charge. Good men are afraid of the guilt of omissions ( I Samuel 12).
We best oppose error by promoting a solid knowledge of the word of truth, and the greatest kindness we can do to children, is to make them early to know the Bible.
He that is in haste may contract much guilt in a little time. What we say or do unadvisedly when we are hot, we must unsay or undo again when we are cool, or do worse.
