Serving God is the highest calling of life. It is a privilege, an honor, and a responsibility above all others. Serving God is rarely something one aspires to from their youth. Rather, it is an endeavor into which one grows. God is always calling out to His creation, beckoning them to fellowship with Him. When we respond, it becomes the highest calling we could ever receive. Nothing else in life could be more intense or deliver in a more profound way.
Our response is often an arbitrary reflex of our free will, but the call itself is an intentional movement of God towards one whom He created. Why the God of the universe would choose to fellowship with one such as myself will be a mystery until the day I can ask Him. For now, I only know it is humbling. It is the highest calling.
