Can you remember a time when you were waiting on a call? Perhaps, it was an offer for a job you really wanted, the acceptance of an offer on a home, or awaiting results from a medical test. Whatever the situation, waiting on that call is hard.
God calls us as well. Sometimes we may feel like his call is taking a long time, or we are not clear on what he is asking, he has the wrong person, or we hear but delay in answering. Then there are other times when God may be grooming us, preparing us for the call.
