One of the biggest dangers for believers is a failure to mature. To grow, we must have nourishment from God’s Word, and to become strong, we need the exercise of obedience.
From Hebrews 5:12-14: “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.”
