This picture speaks of waiting. Have you ever waited for something to happen or manifest? Although we have heard, Good things come to those who wait, waiting can be agonizing. Waiting can be difficult and discouraging!
This picture speaks of loneliness. No one else can truly know how it feels to wait for your desire to manifest. They can only be there with you. Waiting is an experience of isolation. You can be lonely even surrounded by people. "Loneliness is and always has been the central and inevitable experience of every man." (Thomas Wolfe) Loneliness comes with life.
But there is a loneliness which comes from waiting on God. Unless we can find the comfort of solitude our waiting will make us sick. Hope deferred makes the heart sick. (Proverbs 13:1) Learning to wait represents a deeper sense of trust. "What God does in us while we wait is as important as what it is we are waiting for." (John Ortberg)
The loneliness in waiting can draw us closer to God. God teaches us how to wait. But they that wait upon the Lord shall renew their strength. (Isaiah 40:31)
Learning to wait upon the Lord develops a sense of dependency on God. This understanding is closely related to Psalms 127:1, Unless the Lord builds the house, those who build it labor in vain. Unless the Lord watches over the city, the watchman stays awake in vain. We cannot make our desire come to pass but we can trust and rely on God. Such dependency is built when we wait.
