1. The man who was uprooted from the land (1-7)
The man who does not make God his stronghold, but trusts in wealth will be uprooted from the land. Doeg the Edomite (1Sa 22:6-23) was such a man. He was a man who grew strong by destroying others. He boasted of being a mighty man, but his might was based on evil plots and on destructive lies. God will deal with such men in his own time and in his own way. God's people do not have to seek revenge, nor do they need to harbor hatred in their hearts.
2. Like a flourishing olive tree (8-9)
The man who trusts in God's unfailing love will flourish like a fruitful olive tree. David was such a man. He was a fugitive, constantly hunted and harassed by King Saul, but he could say, 'I trust in God's unfailing love forever and ever. I will praise you forever for what you have done'; his hope was in God.
Application: Lord, I trust your unfailing love. Let me flourish like an olive tree.
One Word: Be like a flourishing olive tree
