There is a very common practice among some people known as either:
- "doctor shopping" - keep visiting physicians about a complaint until one receives the answer the patient has already decided
- "expert shopping" - keep asking questions about a problem from a variety fo experts until one receives the answer one wants to hear.
King Saul appears to have been guilty of this, but in his case, it appears his condition might be labelled "oracle shopping".
When he "enquired of the LORD" as recorded in 1 Samuel 28:5-6, he either ignored the answer, or, more probably, God knew that he would ignore the answer and not repent and so the LORD "did not answer". We see this repeatedly - people who are hard of heart or who will ignore the answer (if given) are given no answer by God, eg:
- Ps 18:41, They cried for help, but there was no one to save them-- to the LORD, but he did not answer.
- 2 Sam 22:42, They cried for help, but there was no one to save them-- to the LORD, but he did not answer.
- 1 Sam 14:37, They cried for help, but there was no one to save them-- to the LORD, but he did not answer.
From this we learn that when people asked anything of God, eg, for guidance, they must be in a condition that they are ready to receive and act on the guidance given, else no reply will be provided.
I Chron 10:13, 14 is significant here. The fact that he did enquire of God, but God did not answer, means that it was a waste of time asking because Saul would not have accepted the reply.
