Is Christianity Deep and Profound?

A question that I asked myself at church this morning is this: Is Christianity really that deep and profound of a religion?   My pastor was saying that it is.  And our liturgy and Psalm 139 say that God has numerous thoughts, which we are not able to count.  But, when I look at Christianity, it doesn't strike me as overly deep or profound.  I'm not saying that I know everything or even most things about it and its various manifestations and holy writings.  But I do believe that I have a fairly decent handle on its overall repertoire, and, even when I come across things about it that I do not know, I am not particularly awed, nor do I feel as if I am traveling in very deep waters.  There's enough for me to learn that I can stay entertained by reading and thinking about the Bible.  But the Bible and Christianity do not strike me as particularly deep or profound.

That's all I'm in the mood to write in this post.
