Setting ambitious goals is therefore a good thing, and determining whether or not we are desiring something sinful, or desiring it sinfully, is heart work. We do that heart work by praying to the Lord about it, by reading the Word faithfully, looking to be instructed, and by worshiping God together with His people, gathering regularly to be edified by Word and sacrament. Every week you place all your ambitions on His altar and watch them ascend to Heaven in a column of smoke. When you get to your office Monday morning, they will be there on your desk, cleansed and waiting for you.
