It is wonderful to know that even if I am weak from what I have to deal with, God knows all things including what it is I have to face. Verse 3 is reminding us that we can go through times where we are weak from dealing with issues or other people in life and become worn out. However, that does not mean God is slaking on the job. It just means we are worn out from dealing with stuff. Personally, I have found that by doing things God has called me to do will often refresh me both physically and spiritually.
As a result of living in a sin cursed world, we all have to deal with difficult stuff in our life. God is aware of those things and He is guiding us through what comes our way. We can count on His guidance during all times of our life.
Someone may say, 'I have no idea how to deal with what I am going through.' Besides praying one's way through the situation and doing the things God has called us to do, sometimes it is a matter of trusting God each step of the journey.
The Psalmist says in verse 4, that he looked to his right hand and saw that no one was concerned for him. This verse expresses a feeling most of us know at times. It is that "small violin weeping just for us". It is thinking that no one cares or understands my problems. The truth in life is most people are so wrapped up in their own issues that they don't reach out to help others.
Remember when David wrote this verse, he was hiding in a cave. Most likely he was trying to save his life and hiding out from people would provide a haven of safety from the king who was trying to kill him. This was a scarey and lonely place for David to be in his life.
Verse 5 gives the solution to the Psalmist's loneliness. I cried unto thee, O LORD: I said, Thou art my refuge and my portion in the land of the living. What does he do? He takes the pain and gives it to God. Be reminded that God is perfect; He knows all things and He is completely aware of the fact we are stuck at times in our own "cave".
Does this mean we only need God and not other people? Of course not. God has placed other people in our lives but He alone understands us when others do not and even when we do not understand ourselves. He longs to be our source of comfort. Why not share with Him today?
