One day last week, I wanted to call Carrie (I had been out of town all week). However, I had no agenda. I just wanted to call her. I simply wanted to call in order to feel like I was in her presence, to remind my heart again of what I love about her.
Then I realized this is at least one reason why we pray. We are not yet in the immediate presence of Christ, but we long for him. We want to be in heaven where our fellowship is uninterrupted. Until that day, we pray so that we may get a small taste of his presence and to be reminded why we love and delight in him.
Prayer is to the Christian what a cell phone is to a husband who is travelling, away from his wife, but wanting to be with her.
