“If a man makes a vow to the Lord, or swears an oath to bind himself by some agreement, he shall not break his word; he shall do according to all that proceeds out of his mouth.”
A vow is a form of a promise. The person taking the vow is promising certain actions will follow. This whole chapter is emphasizing the need to be faithful to the promises made to the Lord and to others. The basic idea is that God wants His people to be honest.
Honesty is a foundational principle for healthy relationships. If a person lies they cannot be trusted, and it becomes impossible to build or even maintain relationship with them. As parents, it is critical that we instruct our children on the value of honesty. This is done by both setting an example and establishing certain guidelines. We lie because we think the truth will get us into trouble. We need to encourage truth from our children and help them see that lying is, in many ways, only delaying the inevitable and making things worse.
Honesty is also a critical part of our walk with the Lord. We are easily deceived, and in many cases, not honest with ourselves. When we sin, we are very good about blaming circumstances or other people. We need to take an honest evaluation of ourselves and make the proper changes so we don’t end up falling into the same sin over and over again.
Let’s be sure to allow the Lord to examine us, be willing to confess our faults to Him, and receive His grace to move beyond them.
