Is Christianity an experiential practice? It has been stated to me that Christianity is "experiential" meaning it is experienced and not necessarily understood.  Do I have that definition correct?  Is this true?
Yes, I think it is.  Though, with an emphasis on "necessarily".  Well, beyond the core tenants, anyway.

If you are a Christian but have never experienced God's love, then something is missing.  I'm not talking about charismatic or pentecostal "gifts of the Spirit", I'm just talking about... feeling that God loves you.

Miguel de Unamuno: "Those who believe that they believe in God, but without passion in their hearts, without anguish in mind, without uncertainty, without doubt, without an element of despair even in their consolation, believe only in the God idea, not God Himself”

Disclaimer: this is my understanding, and probably mine only.  I do not speak for any congregation, demonination, or any other -ation.
