We are all gifted with unique aspects of God’s calling. He made us to function in a specific way in the Kingdom. We each have the ability to hear the Lord’s voice so He can develop us into the people we need to be to minister in our own spheres. That probably doesn’t mean going into full-time ministry. It probably means using unique skills and talents to do a certain thing well and not being shy about the presence of God moving through us. It’s important to learn to hear His voice so we know what that calling is.
But that calling isn’t the end all of our lives. If your talent is singing, or finance, or medical research, being the best at that isn’t the goal. God doesn’t care if you are the most gifted singer or scientist. Your calling is just the means He uses to get your attention. He’s after your heart and your obedience. Listening to His voice and obeying His direction today is more important than the goal of success, what ever that looks like. Above all things, love. All will know that you are My disciples, if you have love for one another. (Jn 13:35)
If you are so serious about your ministry/talent/calling that you fail to love those around you, you seriously missed the point of the gospel. Let’s not get so heavenly minded that we’re no earthly good.
