I also thought it was neat in verse 11: "And the Lord said to Samuel: See I am about to do something in Israel that will make the ears of everyone who hears of it tingle." (Samuel 1:11)
You know when somebody is about to tell you a secret--especially when they whisper it into your ear, your ear and your whole side of your body kinda gets that little goosebumpy feeling? It's exciting. It's an exciting feeling because it's something you've never heard before whether good or bad news. Just imagine how much more of that tingling sensation you'd get when God wants to share a secret exclusively with you. *tingle* ..hehe
On a last note, I also wanted to point out the obedience of Samuel. When Eli realized that Samuel was hearing the voice of God, he told Samuel to go back to bed and lie there and just accept and submit to the Lord's calling. And that's exactly what Sam did. "Then Samuel said, "Speak, for your servant is listening." (Samuel 1:10) I hope and pray that we could all learn a thing or two from Sammy and just obey the Lord and listen to whatever He has to say with eager hearts.
