Reading 1st Samuel

Something really interesting occurred to me as I was reading 1st Samuel
1 Sam 3: 7 says that 'Samuel did not yet KNOW the Lord: the word of the Lord had not yet been revealed to him'
BUT
BEFORE THAT
in 1 Sam 3:1 it says that 'the boy Samuel ministered before the Lord under Eli'
and we know that his mother brought him to the temple as soon as he was weaned, and therefore even though Samuel grew up in the church, and ministered and helped the priest he still did not KNOW the Lord!!
IT was just a amazing reminder that when you hear people talk about growing up in the church or EVEN helping and ministering in the church it means nothing as proof of their faith.
One can do all of those things and still not KNOW God.
