There may be times when people have risen to the occasion when given responsibilities when they had shown little responsibility previously--but this is the exception to the rule. The one who cannot or will not keep pace with the footmen cannot match the speed of horses. Until people have a genuine change of heart and mind, they will continue to do as the Steely Dan song goes: "You go back, jack, do it again...wheel turning round and round." In the song a man swears he is not a gambling man, but finds himself back in Vegas with a handle of a slot machine in his hand and playing cards with hopes to win big money. What people say is no guarantee they will ever do as they say. From history and experience, it is more likely the opposite will eventually be true.
In 2 Chronicles 15, Azariah the prophet spoke to king Asa of Judah and encouraged him to seek the LORD, to exert his strength to put away idols in his kingdom and turn to God. The king and people did so with one heart, and Israelites from the northern kingdom flocked to Asa in Jerusalem because they saw God was with him. Asa removed idols from Benjamin and Judah, restored the altar of God, and offered many sacrifices to the LORD. In the fervor of this revival the people made a covenant with God, an oath that whoever among them who would not seek the LORD would be put to death. They rejoiced to make this promise because they sincerely did so with one heart, and the LORD was found by them.
There is nothing wrong with the enthusiasm the people showed in seeking the LORD, but the oath they made with God certainly raised my eyebrows: they had not been faithful to keep God's law concerning executing idolators (Deuteronomy 13:6-18), yet they would go beyond the Law of Moses to execute anyone who did not seek the LORD ? What was their definition of "seeking" God? How was this determined? Any metric for discerning this likely boils down to appearances, what a person does or does not do--and cannot address the heart. This passage shows enthusiasm for God, sacrifice, unity in a cause and oaths uttered before God does not provide the ability to follow through and keep promises. As Samuel told Saul, "To obey is better than sacrifice." It is better to heed God's word and follow it than put ourselves under oaths to require more of ourselves than God does--as if our oath is more important than God's commands.
The failure of Asa and his people to obey God's law (much less their oath) is found in the passage that immediately follows in 2 Chronicles 15:16: "Also he removed Maachah, the mother of Asa the king, from being queen mother, because she had made an obscene image of Asherah; and Asa cut down her obscene image, then crushed and burned it by the Brook Kidron." Maachah was removed from her royal duties (which was unprecedented under previous kings) but still stopped short of obedience to God's law. Under law, what was done to her obscene idol is what ought to have been done to her. I do not fault Asa for what he did, but in his actions we see the folly of thinking we are capable to do ourselves more than God requires of us. If I cannot bench press 100 kilos, it would be silly to load the bar with an additional 200 kilos and imagine I can rise to the challenge because the stakes are higher.
James 5:12 teaches us, "But above
all, my brethren, do not swear, either by heaven or by earth or with any other
oath. But let your "Yes," be "Yes," and your "No," "No," lest you fall
into judgment." James tells us what we don't think we need to hear, for like Asa and the people, we easily slip into making promises we do not keep. We have a tendency to put our word above God's word in a sense, making more of an effort to keep our word for the sake of our pride and keeping up appearances rather than simply obeying God's word for His sake and glory. There is no point in saying we will do God's will if we will not do it. God's desire is that without making promises we would heed His word and walk in His ways because of what He has said, we love Him and delight in seeking Him. Talk is cheap, but what we do speaks truly.
