What Would Be the Net Effect?

Mark Lauterbach keeps hitting it hard in his series on prayer (emphasis mine):

One friend of mine, a missionary in Rwanda, recalled to me the day when he was asked, "If God answered all your prayers today, what would be the net effect?" His answer was simple -- he would be happy and healthy and stress free and so would all his friends and family. He was convicted of the selfishness of his praying! He was not asking for conversions, for godliness, for new churches, for new leaders. He was asking for his own comfort.

I find this to be the one core condition -- am I seeking from God those things which are most on his heart? I know his heart by studying Scripture and knowing what Christ died for . . . and that is Gospel-driven praying.
