I will extol you, O LORD, for you have drawn me up and have not let my foes rejoice over me.  O LORD my God, I cried to you for help, and you have healed me.  O LORD, you have brought up my soul from Sheol; you restored me to life from among those who go down to the pit.  Sing praises to the LORD, O you his saints, and give thanks to his holy name.  For his anger is but for a moment, and his favor is for a lifetime. Weeping may tarry for the night, but joy comes with the morning.  As for me, I said in my prosperity, “I shall never be moved.”  By your favor, O LORD, you made my mountain stand strong; you hid your face; I was dismayed.  To you, O LORD, I cry, and to the Lord I plead for mercy:  “What profit is there in my death, if I go down to the pit? Will the dust praise you? Will it tell of your faithfulness?  Hear, O LORD, and be merciful to me! O LORD, be my helper!”  You have turned for me my mourning into dancing; you have loosed my sackcloth and clothed me with gladness,  that my glory may sing your praise and not be silent. O LORD my God, I will give thanks to you forever! (Psalm 30 ESV)
Everybody Sing (4-5)
After expressing praise to God for his healing and rescue, David naturally calls on God’s people (O you his saints), to sing and give thanks to God for his reliable rescue. While it is true that God disciplines sin in the lives of his people (Hebrews 12) his anger toward it doesn’t last forever. His mercy comes to us as surely as the sun rises in the morning. While it is also true that this world and our bodies are broken and disease and pain are wrecking our lives, and we are surrounded by broken relationships, broken promises, broken financial stability, and broken plans for the future, brokenness is not forever. There will be healing, either in this life or at the end of it.
Joy Comes in the Morning
In this, the year of Hope, joy arrives as sure as the sun rises. If you are a believer in Jesus, then your hope is not based on broken things, but on God who fixes broken things.
 For I consider that the sufferings of this present time are not worth comparing with the glory that is to be revealed to us.  For the creation waits with eager longing for the revealing of the sons of God.  For the creation was subjected to futility, not willingly, but because of him who subjected it, in hope  that the creation itself will be set free from its bondage to corruption and obtain the freedom of the glory of the children of God.  For we know that the whole creation has been groaning together in the pains of childbirth until now.  And not only the creation, but we ourselves, who have the firstfruits of the Spirit, groan inwardly as we wait eagerly for adoption as sons, the redemption of our bodies.  For in this hope we were saved. Now hope that is seen is not hope. For who hopes for what he sees?  But if we hope for what we do not see, we wait for it with patience.
(Romans 8:18-25 ESV)
