Hannah named him Samuel "because I have asked him of the LORD", 1Sam1:20. Similarly we find that when Elisha wanted the double-portion of Elijah's spirit that it would only be IF he "saw him when he ascended on high". 2K2:10. Until we SEE it in the Scripture for ourself, and ASK for the Holy Spirit, it won't be ours. The Apostle Thomas wasn't present when Jesus showed the others the evidence of his hands and side, John20:20, and he wouldn't believe their testimony, but declared he would have to see for himself. Precisely what I'm thinking -- this is too important to just take somebody else's word for it -- I've got to see it in the Bible for myself!
Elisha stuck to Elijah and wouldn't let him out of his sight, though he knew Elijah would be departing. Surely if someone had a gift that we desired, we wouldn't go to someone else, would we? Would you go to a synagogue or a mosque to find Salvation in Christ Jesus? How will you ever detect the counterfeit if you don't know the document that they emulate?
Note that Samuel's lifetime divided the period between the Judges and the Kings -- note also that his name is UNIQUE -- for some strange or perverse reason none of the New Testament children were given the notable names of Adam, Noah, Job, Samuel, Ruth, etc. The repetitive names, like James or Joseph, stand in contrast to this curious feature of Scripture.
Luke11:13 "If ye then, being evil, know how to give good gifts unto your children: how much more shall your heavenly Father give the Holy Spirit to them that ask him"?
