If your TO DO list is growing and your time is shrinking and you don't see how you are going get it all done; you need to hear David sing his song again, the one about God's amazing power:
You save the humble
but bring low those whose eyes are haughty.
You, Lord, keep my lamp burning;
my God turns my darkness into light.
With your help I can advance against a troop;
and by my God I can leap over a wall.
As for God, his way is perfect:
The Lord’s word is flawless;
he shields all who take refuge in him.
And then soak up Tozer's words again, the ones about impossibilities and prayer:
You may feel hemmed in by that tall wall of responsibilites surrounding you, but your wall is no match for God and prayer.
