Since then we have a great high priest who has passed through the heavens, Jesus, the Son of God, let us hold fast our confession. For we do not have a high priest who is unable to sympathize with our weaknesses, but one who in every respect has been tempted as we are, yet without sin. Let us then with confidence draw near to the throne of grace, that we may receive mercy and find grace to help in time of need. (Hebrews 4:14-16 ESV)

A prayer from The Valley of Vision, a book of Puritan prayers and devotions:

O God of my delight,

Your throne of grace is the pleasure ground of my soul. Here I obtain mercy in time of need, here see the smile of your reconciled face, here joy pleads the name of Jesus, here I sharpen the sword of the Spirit, anoint the shield of faith, put on the helmet of salvation, gather manna from your Word, am strengthened for each conflict, nerved for the upward race, empowered to conquer every foe.

Help me to come to Christ as the foundation head of descending blessings, as a wide open flood-gate of mercy.

I marvel at my insensate folly that, with such enriching favors within my reach, I am slow to extend the hand to take them.

Have mercy upon my deadness for your name’s sake.

Quicken me, stir me, fill me with holy zeal. Strengthen me that I may cling to you and not let you go. May your Spirit within me draw all blessings from your hand. When I advance not, I backslide.

Let me walk humbly because of good omitted and evil done. Impress on my mind the shortness of time, the work to be engaged in, the account to be rendered, the nearness of eternity, the fearful sin of despising your Spirit.

May I never forget that your eye always sees, your ear always hears, your recording hand always writes.

May I never give you rest until Christ is the pulse of my heart, the spokesman of my lips, the lamp of my feet.
