In a way, though we have graduated from childhood, as adults, we still struggle to learn this lesson. Let's look at a Biblical example of this, then some modern-day applications.

Having been crowned the masterpiece of His creation, God placed the first couple in their new home. They were free to eat of anything found in the garden. However, the tree of the knowledge of good and evil was off limits. We also know, from v. 22, that in the garden was also the tree of life. They were free to eat of this tree's life-giving fruit. What more could they have desired? They had more than enough! In the perfect state they were in, they could have eaten and lived forever in fellowship with God. Yet, we know what happened (3:1-7), the punishments they had to have (3:16-19), and the consequences for their actions (3:22-24). The problem: they were not content with what God did give them. Instead, they focused on what was forbidden. In short, they wanted more.

Sadly, we aren't through suffering from failing to learn this lesson.

-  Man isn't content with God's simple plan of salvation. He has to either add other things to it, or remove what he doesn't like.

-  We aren't content with God's simple revealed organization of the church. No sir, we have to have all these bureaucratic layers of officers & committees. Or, we entrust all the power into one man, the "pastor."

-  Man isn't satisfied with the simple plan God has left for the work the church is to do. We have to "help" God out by adding things He has not authorized the church to engage in, or we "farm out" work the church is to be doing to humanly-devised institutions.

We have all we need (2 Pet. 1:3). Are you happy with that?
