There are at least two limits to a father's discipline:
His discipline or education lasts only a few years—children eventually leave home.
Fathers do their best with limited understanding.
In contrast, God's discipline lasts a lifetime and is always beneficial, based on his infinite knowledge and love. His goal is for us to share in his holiness. Although discipline is painful, it leads to a peaceful life of doing right. It helps God's children build harmonious relationships and make good choices (see also Romans 5:3–4; 8:17, 28; 2 Corinthians 4:17; Philippians 1:12–14; James 1:2–4; 1 Peter 1:7; 4:14).
