To pray is to talk to the Lord. When we are filled with the HolySpirit we talk to Him who is GodInUs.
What are holy hands? It is -> realization of the HolySpirit in us -> a life that avoids doing selfish, mean things.
What is without wrath? It is -> realizing there is no condemnation on us -> a life absent of bitterness.
What is without doubting? It is -> having the FaithOfChrist in us -> believing in the goodness of the Lord to the extent that we believe and receive His promises in His Word.
After all, if the Lord has given us His HolySpirit what will He withhold?
For His nature, His gifts and His beauty we aught to praise Him.
To praise our Lord Jesus Christ is good for us.
