Nevertheless I have somewhat against thee, because thou hast left thy first love.
Remember when you were first saved? That on-fire, totally consuming, single focus of your attention? Then over time, that changed. You were not as excited about what Christ did for you. I am not saying you still don't appreciate it. I am saying that you don't feel the on fire, consuming need to share that information with everyone you meet.
Christ wants us to return to that on-fire, all consuming, single focus. Does that mean you can neglect everyone or everything else in your life? Not at all. But as we mature in life and in our salvation we should learn to do both. Do you talk to someone about Christ every day? At least for a few minutes? Do you read His word every day? At least for a few minutes? Do you try to learn something new about Christ every day? Or do you think you know it all? I know I don't know all there is to know about Christ, and that it will take me the rest of my life to learn of Him and I still won't know all there is to know. Think back to when you were newly saved. You read the bible every chance you got to learn more of Him. You told everyone you met about the wonderful Savior you had found. That is the first love Christ is calling us back to.
