Give unto the LORD the glory due unto His name; worship the LORD in the beauty of holiness. – Psalm 29:2

Prayer is no trifle. It is an eminent and elevated act. It is a high and wondrous privilege. Under the old Persian Empire a few of the nobility were permitted at any time to come in unto the king, and this was thought to be the highest privilege possessed by mortals. You and I, the people of God, have a permit, a passport to come before the throne of heaven at any time we will, and we are encouraged to come there with great boldness; but still let us not forget that it is no mean thing to be a courtier in the courts of heaven and earth, to worship Him who made us and sustains us in being. Truly, when we attempt to pray, we may hear the voice saying out of the excellent glory: “Bow the knee.” From all the spirits that behold the face of our Father who is in heaven, even now, I hear a voice which saith, “Oh, come let us worship and bow down, let us kneel before the Lord our Maker; for He is our God, and we are the people of His pasture and the sheep of His hand. O worship the Lord in the beauty of holiness; fear before Him all the earth.”

We are still on praying ground and pleading terms with God, and the throne to which we are bidden to come…is the throne of grace. It is a throne set up on purpose for the dispensation of grace; a throne from which every utterance is an utterance of grace; the scepter that is stretched out from it is the silver sceptre of grace; the decrees proclaimed from it are purposes of grace; the gifts that are scattered down its golden steps are gifts of grace; and He that sits upon the throne is grace itself. It is the throne of grace to which we approach when we pray; and let us for a moment or two think this over, by way of consolatory encouragement to those who are beginning to pray; indeed, to all of us who are praying men and women.~ C.H. Spurgeon
