Don't be too severe
Eph 6:4 Fathers, do not exasperate your children; instead, bring them up in the training and instruction of the Lord.
Likewise Paul writes, "Fathers, do not embitter your children, or they will become discouraged." Col 3:21 While there are fathers who take little interest in their children, those who love their children have to be careful not to be too overbearing and demanding, or just plain annoying. Children are more emotionally fragile and impressionable than adults. Mothers are more in tuned to the emotional aspects of raising children, and by nature are generally more gentle than fathers. But children tend to listen to their father more so than to their mother. So fathers keep this is mind, your children may take you more seriously than you think. A passage related to this verse, that may be instructive to us all as we are being trained as children of God is Heb 12:5-11
"'My son, do not make light of the Lord’s discipline, and do not lose heart when he rebukes you, because the Lord disciplines those he loves, and he punishes everyone he accepts as a son.' Endure hardship as discipline; God is treating you as sons. For what son is not disciplined by his father? If you are not disciplined (and everyone undergoes discipline), then you are illegitimate children and not true sons. Moreover, we have all had human fathers who disciplined us and we respected them for it. How much more should we submit to the Father of our spirits and live! Our fathers disciplined us for a little while as they thought best; but God disciplines us for our good, that we may share in his holiness. No discipline seems pleasant at the time, but painful. Later on, however, it produces a harvest of righteousness and peace for those who have been trained by it."
So fathers, discipline your children, but do not exasperate them.
