They are busy. They are practicing religious activities while living the whole of their lives on the world's terms. Their hope is in their fleshly accomplishments and they are left disappointed. They are asking God to bless their efforts, but they are not allowing God to direct their lives. They are not filled with the Spirit of the living God.
Churches try to fill the void in member's lives through buildings, entertainment, and activities.
The gospel is preached as a means to health, wealth and prosperity. We convince people they can start a business as a ministry to people and become wealthy as they serve God. Although we are impotent to fill the vacuum ourselves, we are not helpless. God is hoping we will turn to him when we come to the end of ourselves. God allows us to fail as we search the endless vacuum inside our hearts for answers.
