The whole world longs for a hero, someone who would save us all from the enemy and the hardships of life. You just need to read comics and children stories to find out that the world is preoccupied with heroes. We grew up with heroes like the Spider Man, Batman, Superman, Hercules, Sinbad just to mention a few.
When you try to serve God without having a personal revelation of Him or experiencing intimacy with Him, you serve Him with your own strength. While this might work for some time, it will fail in the end. Your relationship with Him will begin to go stale and produce no lasting results for you. Others may be blessed by your ministry but you yourself will not be. There will always be something lacking and the joy for ministering to the Father will be lost. You'll quickly be burned out as your passion for Him and souls dissolve in the sea of trails and the cares of this world.
Love is a very essential human need. Everyone wants to be loved. Love is not just a want but a need that ought to be satisfied. Every human being without exception needs love, that is the way we have been created. Love is not limited to race or social status. The need to be loved in man does not diminish with time or age.
