This document discusses the concept of mystery, groaning, and longing in relation to faith. It states that there are things that are unknown or unexplained, which is where God comes in. It also says that miracles happen in mystery. Groaning and longing come from both suffering in the present world and from desiring the future redemption promised by God. The Holy Spirit helps believers with "groanings that cannot be uttered" and lifts them up to a better perspective.
