Ecclesiastes 5:4-5 – 4 When you make a vow to God, do not delay in fulfilling it. He has no pleasure in fools; fulfill your vow. 5 It is better not to vow than to make a vow and not fulfill it.
However, when you do vow and obey the Lord, it pleases Him greatly. If we’re not trying to please the Lord, we need to examine and question our path.
