This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins. Dear friends, since God so loved us, we also ought to love one another. (1 John 4:10-11)
I've heard people say quite often: "it all boils down to this: Love God and Love People." And after all, that's what Jesus said. But to me the very next question is always: well, then, how do I love God? In fact, it usually sounds very burdensome to me: I know I must love God...God, how can I love you? I want to love you so much, but I'm always failing! God, I feel like such a failure!
But perhaps the key to Loving God and therefore to loving others isn't "how do I love God?" at all. 1 John 4 says the key is "do you know God's love for you?" And then the task becomes really knowing and grasping that radical love...which is the most counter-intuitive thing to do in the world. And then perhaps we can love God...and then perhaps we can love others.
