So our carnal, evil heart that puts its trust in itself, our self, results in a shrub, thirsting in a desert, a salt-like land that is barren and uninhabitable. When our heart is focused on getting what we want, what we treasure, what we think about all the time, our heart actually goes to thinking that it knows best, and we depart from the Lord, and we wither like that grass burned and scorched in the sun. As we examine our heart, what is it that is taking our attention away from God? Do we have a bad attitude about something we think we should have that God has not yet given to us?
In other words, the person who does not live by faith is not going to grow. He is going to be like a shrub in the desert that only receives water every so often, not near often enough to really grow.
