If you need some encouragement, here are two amazing sermons by John Piper.
"Don't be like the person who goes to the Grand Canyon with a little garden shovel in his hand, and on the precipice of that majesty turns his back to the Canyon, kneels down, and digs a little trough with his shovel and shouts, "Hey, look at this! Look at my trough! Isn't that cool!" I know that the pressing and desirable things of your life seem big. But just a little clearheaded thought will show you they are not. Get up and turn around and look at the Canyon."

6. Verse 13: There is a true king on the throne who has the reign in the castle: God.

7. Verse 13: There are weapons in the castle that can be used to advance the cause of the true king, God, or the cause of the pretender to the throne, sin: members [parts] of the human body. "Do not go on presenting the members of your body to sin as instruments [o[pla, weapons] of unrighteousness; but present yourselves to God as those alive from the dead, and your members as instruments [o[pla, weapons] of righteousness to God."
