I frequently will have these moments when seemingly out of nowhere someone will pop into my mind. I'll think through certain memories I have of them, and often wonder where they are and what they're doing now, if I don't already know.
Sometimes I wonder if the Lord puts people on my heart and mind just to pray for them. Perhaps, he places them on my heart and mind to pray for them even when I have no idea what I'm praying for. Then, I think that it would be nice if they knew that someone was thinking of them and praying for them.
It does seem significantly special to someone when they know that someone else is thinking about them, and especially praying for them. It seems that, perhaps more than anything else, to make someone feel special is just to let them know that you're thinking of them. I have found that to do this requires me to not worry about their potential reaction to me telling them I'm thinking about them.
So, when the Lord brings someone to my heart and mind, I'm going to try to make it a point to let them know. Even if all I say is, "I'm thinking about you and praying for you", it has the potential to make their day, week, or even year. What an easy way to cheer someone up! And, perhaps, in praying for them, the Lord uses it in some ultra-significant way to alter the course of their lives.
