“The righteous shall flourish like the palm tree: he shall grow like a cedar in Lebanon. Those that be planted in the house of the Lord shall flourish in the courts of our God. They shall still bring forth fruit in old age; they shall be fat and flourishing” (Ps 92:12-14).
According to these verses God’s children, his righteous ones, are going to flourish. We will have long, useful and fruitful lives. Not only that but we will grow old gracefully and still be fruitful and contented in old age. Now that is a promise!
However, all of this is also dependent on something, which is found in verse 13. In verse 13, we see that the condition is that we have a heart’s desire to be planted in his house and flourishing in his courts.
Does that mean we have to live in church all week? I don't think so. What that means is that we need to be in the presence of God as much as possible and then all these wonderful promises will be the result of that. Being in God's presence doesn't mean you have to spend all day on your knees; you can be mindful of his nearness while you are at work, shopping, doing chores or whatever. We can fellowship with God wherever we are and whatever we are doing. We need that desire for a close relationship and intimacy with him.
