Desire

"Delight yourself in the LORD, and He will give you
 the desires of your heart. Commit your way to the LORD, trust also in Him, and He will do it. " (Psalm 37:4,5) 
Sometimes I treasure up desires in my heart.  I allow my mind to fantasize about the future, which, though not damaging in and of itself, can lead to a self-centered focus.  If on the other hand, I rest on Jesus, and desire His will, the future becomes not about me but about Him.  When I mold my desires to His, when I commit myself to abiding in Him, when I realize the future is in His hands, I am at peace.  If you learn to commit your desires to Him, and desire Him first, then His desires will become your desires.
"Now to Him who is able to do far more abundantly beyond all that we ask or think, according to the power that works within us, to Him be the glory in the church and in Christ Jesus to all generations forever and ever. Amen." (Ephesians 3:20-21)
