Duration of the stay

How long should I stay has been rolling around inside of me this past few days.
What the Lord shared with me was: Before the foundations of the world, a plan was written for each and every life and every day. It is reaching an understanding that we can “alter” that plan by the decisions we make. Today as I walked and prayed, I realized that I must stay here until each and every appointment that was prewritten is fulfilled or I’m accountable when I arrive in heaven for deciding that my plan was more important that the plan that was written. That would leave me in a place of being outside of the will of God. Not a place any of us should be interested in being.
