If a man vows a vow to the LORD, or swears an oath to bind himself by a pledge, he shall not break his word. He shall do according to all that proceeds out of his mouth.
God expects and appreciates complete honesty in keeping the commitments we make to Him and to other people. That is why pledging an oath is very serious business. God is truth. And He expects human beings to be truthful. It is the clearest sign of our fallen depravity that we find the keeping of an oath so very hard to do and so easy to shirk off as unimportant.
But today oaths are pointless and broken without much thought. We casually promise. Vows are cheap and easy as well, which is why divorce is rampant and marriage is disdained. The culture of “hook-up, shack-up, and break-up” (Mark Driscoll) exists because no one will commit the moral backbone to enter into a real commitment in a relationship. Often it is the guy who is spineless and the woman who is frustrated but enables it anyway because in her mind it is better than nothing.
People will not commit to God at all and they will not commit to each other without a string of lawyers in tow. What chance do we have at remedying this? There was one person who fulfilled God’s promises to save us: Jesus. He can redeem all our sins and broken promises. He can salvage souls and make us people of our word. He can mend marriages. He can fix families. He is a real and living hope in a world of broken promises made by broken people.
