On having to wait
“Waiting is very difficult for most people, for it is an admission that there is nothing we can do at the moment to achieve our ends. Yet that admission is the first requirement for spiritual blessing” (From Oswalt’s Commentary of Isaiah).
Have you ever thought about why people hate waiting? Oswalt is suggesting it is not about impatience but rather about self-sufficiency. Waiting tells us that we are not completely independent, we cannot control everything or everybody, and we are not self-reliance. It is a blow to our pride to have to wait and be dependent on something or someone else.
Perhaps this is why God often keeps us waiting, to teach us our limitations and our need of him.
