How do we know that God deals with us as sons?

The epistle to the Hebrews affirms that if we endure chastisement, it is evidence of our status as God's children (Hebrews 12:7). As a father corrects his children, God corrects us not to disown us but to mold us and lead us towards righteousness. This divine correction and guidance are marks of our sonship. It demonstrates that we are not illegitimate children but are accepted members of His family, experiencing His discipline and instruction in our spiritual walk. A true son learns obedience and grows through the trials and teachings imposed by a loving father.
