The process of spiritual growth may be depicted in various ways, depending upon what yardstick you use for measurement. Here's a not-so-precise depiction:
(1) You search for God to fill the void in your life.
(2) You find Christ, believe in him, and life becomes meaningful. You still learn more and more about him.
(3) You finally know the Lord so well that there is no more questioning, doubting. You fully embrace him and he is no longer mysterious to you. You happily follow him everywhere at all times.
