This Psalm has been used in some very significant ways throughout church history. In the Easter Orthodox Church, it is read while the priest stands behind the Royal Doors that separates him from the altar. This is because this Psalm is believed to be a Psalm of Adam and spoken while he was on the outside of the gates looking into the Garden of Eden where he was expelled from.
