Are you worried about the Dow Jones?

This psalm is a prayer for the kings of Israel, but with relation to Christ. - Even the greatest of men may be much in trouble. Neither the crown on the king's head, nor the grace in his heart, would make him free from trouble. Even the greatest of men must be much in prayer. Let none expect benefit by the prayers of the church, or their friends, who are capable of praying for themselves, yet neglect it. Pray that God would protect his person, and preserve his life. That God would enable him to go on in his undertakings for the public good. We may know that God accepts our spiritual sacrifices, if by his Spirit he kindles in our souls a holy fire of piety and love to God. Also, that the Lord would crown his enterprises with success. Our first step to victory in spiritual warfare is to trust only in the mercy and grace of God; all who trust in themselves will soon be cast down. Believers triumph in God, and his revelation of himself to them, by which they distinguish themselves from those that live without God in the world. Those who make God and his name their praise, may make God and his name their trust. This was the case when the pride and power of Jewish unbelief, and pagan idolatry, fell before the sermons and lives of the humble believers in Jesus. This is the case in every conflict with our spiritual enemies, when we engage them in the name, the spirit, and the power of Christ; and this will be the case at the last day, when the world, with the prince of it, shall be brought down and fall; but believers, risen-from the dead, through the resurrection of the Lord, shall stand, and sing his praises in heaven. In Christ's salvation let us rejoice; and set up our banners in the name of the Lord our God, assured that by the saving strength of his right hand we shall be conquerors over every enemy.

Psalm 20

 May the Lord answer you when you are in distress;
    may the name of the God of Jacob protect you.
² May he send you help from the sanctuary
    and grant you support from Zion.
³ May he remember all your sacrifices
    and accept your burnt offerings.
⁴ May he give you the desire of your heart
    and make all your plans succeed.
⁵ May we shout for joy over your victory
    and lift up our banners in the name of our God.

May the Lord grant all your requests.

⁶ Now this I know:
    The Lord gives victory to his anointed.
He answers him from his heavenly sanctuary
    with the victorious power of his right hand.
⁷ Some trust in chariots and some in horses,
    but we trust in the name of the Lord our God.
⁸ They are brought to their knees and fall,
    but we rise up and stand firm.
⁹ Lord, give victory to the king!
    Answer us when we call!
