Surrounded by guests at his birthday banquet, King Herod swore to the dancing girl that he would give her whatever she wanted, even up to half his kingdom. Prompted by her mother, she asked for the head of John the Baptist on a platter.
Grieved at her request, but because his oath was made in front of all his guests, he agreed. And John was killed.
Keeping your promise or staying with your original decision is a usually a good idea. Far too many promises are made and broken these days.
But sometimes the initial decision, like Herod’s, is faulty. For many people, it’s just easier to stay with the first decision, rather than go to the trouble of attempting a new solution. Additionally, the desire to save face and avoid embarrassment fights against admitting that a change is now needed. This is pride and foolish consistency.
