Lord, in my heart I plan my course, but You determine my steps (Proverbs 16: 9).  Life is not going as I planned.  I am grateful that You are not caught off guard.  You knew everything that would befall me.  Please direct my steps as You determine.  I need You, Lord.  Carry me when I cannot walk.
I want to trust in You, Lord, with all my heart and lean not on my own understanding; in all my ways I will acknowledge You, and You will make my paths straight (Proverbs 3: 5-6).
My God is in heaven; He does whatever please Him (Psalms 115: 3).  Lord, sometimes my only answer will be that You are sovereign.  Your Word says that the death of Your saints is absolutely precious to You (Psalms 116: 15).  One day I will have all the answers.  Until then, I must trust that You have power and dominion over all things and that You know best.  Help me to believe this even when I don't feel this.
I cry to You, Lord, in my trouble.  Save me from my distress (Psalms 107: 13).
I desire to dwell in the shelter of You, the Most High.  I will rest in the shadow of the Almighty. I will say of You, Lord, "You are my refuge and my fortress, my God, in whom I trust." (Psalms 91: 1-2).
So we do not lose heart. Even though our outer nature is wasting away, our inner nature is being renewed day by day. For this slight momentary affliction is preparing us for an eternal weight of glory beyond all measure, because we look not at what can be seen but at what cannot be seen; for what can be seen is temporary, but what cannot be seen is eternal. (2 Corinthians 4:16-18)
Do not fear, for I have redeemed you; I have called you by name, you are mine. When you pass through the waters, I will be with you; and through the rivers, they shall not overwhelm you; when you walk through fire you shall not be burned, and the flame shall not consume you. For I am the Lord your God, the Holy One of Israel, your Savior. (Isaiah 43:1b-3a)
So do not fear, for I am with you; do not be dismayed, for I am your God. I will strengthen you and help you; I will uphold you with my righteous right hand. (Isaiah 41:10)
Create in me a clean heart, O God, and put a new and right spirit within me. Do not cast me from your presence or take your Holy Spirit from me. Restore to me the joy of your salvation, and grant me a willing spirit, to sustain me. (Psalm 51:10-12)
