Rather we unite in praise for a gracious Father who blesses us so richly. Sometimes we weep humbly at His inexpressible goodness. Those are cherished times. We want to cultivate in every family member an appreciation for the divine goodness that blesses and guides our lives. We want our children to feel a bond with God.
Bribes distract from eternal reasons.
Relationships are the reasons. Parents can teach children the grammar of relationships. For example, a parent asked me how to motivate a balky son to wash the dishes. It depends on why the child doesn't do dishes and what is motivating for that child and the quality of your relationship. One child may have a particular dislike for washing dishes and it may be wise to trade some other chore for the washing of dishes.
