Two wrongs do not make a right. A Vow does not make an action right if it would be evil without it. It is better to avoid another mistake than to have two mistakes which we must correct. Be sure what is right before pledges are made or action is taken. Then it may be safe to go ahead.
Rash decisions are troublesome, wasteful and very foolish.
While it is not good to unnecessarily put off decision making, it is an even greater mistake to rush headlong into decisions which may seriously affect you for the rest of your life, without first allowing plenty of time for serious thought and prayer. If you are not yet a Christian, the first step in making the right kind of decisions lies in placing your life in a correct relationship with God so that your prayers may be effective.
