We have much to say about this, but it is hard to make it clear to you because you no longer try to understand. In fact, though by this time you ought to be teachers, you need someone to teach you the elementary truths of God’s word all over again. You need milk, not solid food! Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil. – Hebrews 5: 11-14
I know you remember that one. It is the one about the master who leaves town and gives five bags of gold to one servant, two bags of gold to a second servant, and one bag of gold to the third servant. The first servant invests the gold and doubles his profit. When the master returns he has ten bags of gold. The second servant does the same and produces four bags of gold. The third one is afraid because the master is demanding. He buries his bag of gold because he fears he might lose it if he risks using it.
Many of us are like that third servant.
