Isaiah 40:28-31 NIV 28 Do you not know? Have you not heard? The Lord is the everlasting God, the Creator of the ends of the earth. He will not grow tired or weary, and his understanding no one can fathom. 29 He gives strength to the weary and increases the power of the weak. 30 Even youths grow tired and weary, and young men stumble and fall; but those who hope in the Lord will renew their strength. They will soar on wings like eagles; they will run and not grow weary, they will walk and not be faint.

God is still good, no matter what you face.  God is aware of everything that you may have experienced yesterday, and will experience today and tomorrow.  God has all power, and His understanding is above your comprehension. God knows about your pain, heartache, disappointment, and your sickness.  God never gets tired of listening to your cares.  Although you may have to wait to see how God will answer your prayer, He provides strength during this time of waiting.
