Hebrews 12:5-8

And you have forgotten the exhortation that addresses you as sons: My son, do not take the Lord’s discipline lightly or lose heart when you are reproved by him, for the Lord disciplines the one he loves and punishes every son he receives. Endure suffering as discipline: God is dealing with you as sons. For what son is there that a father does not discipline? But if you are without discipline — which all receive  — then you are illegitimate children and not sons.
