Psalm 86:7 In the day of my trouble, I will call to you, for you will answer me.
This is trust and confidence and hope in God.
David knew God. He knew he could call out to God for anything and everything, in times of trouble and despair, times of worry, fear, pain, suffering
He knew God heard him and he knew God would answer him
in God's perfect timing and will
To have that confidence and hope, even in the midst of sadness and despair and suffering
but I can truly say yes, Lord, I know you will answer me because you have done so all through my life as I have called out to you. Thank you Lord.
