When I say I want to do something without engaging my choice to move on it, I deceive myself. We rule our choices and then our decisions rule us.
I can come to the table with a whole list of wants yet never choose. All my best intentions only paint an ideal rather than deliver results.
The one in God is given the desires of God's heart. Yes, the Lord implants His own desires in us and then He leads us to fulfill those desires for Him through us.
