Before he receives any answers to his prayer, he asks the Lord to restore his joy. The nearer we are to the Lord, the greater will our joy be.
Joy is not dependent on circumstances; we receive joy from being close to the Lord. David is asking God to draw him closer to he has this joy. David could not get it himself; he needed God to do it.
If you are in a despondent state, or even in normal life, we cannot muster joy in ourselves, and the more discouraged you are, the less you are able to draw close to God to receive the joy.
When we pray for our circumstances, don’t wait for the answer before you ask God to restore your joy. You can have joy while you wait for the results of prayer.
Don’t wait for your life to be perfect before you start enjoying it.
Sometimes we may not like where we are, so we can’t enjoy what we DO have, while we wait for what we want. If you won’t like your life until you get a different job, meet someone, or even feel better, then 10-20-30 years are going to pass and you wouldn’t have enjoyed them.
Let God give you joy while you wait. Enjoy what you do have, don’t lament what you don’t! Or your life will be over and you will have missed the good things God HAS given you.
Why should you want and have joy?
Because of the things, we have. Because of God’s blessings?
