Read Why Your Spiritual Growth Matters, by Daniel Darling, at Cross Walk.
"The truth is that there are may Christians who are still spiritual infants, who haven’t grown much in the last few years, and still need milk. And here’s the tragedy of this, really. God has created each of us to a mountain of spiritual nourishment, a conduit of His grace to others. But when we fail to grow, we can’t feed others. We can’t help build the church. We can’t be a light in our communities. This was the concern of the writer of Hebrews:"
12 For though by this time you ought to be teachers, you have need again for someone to teach you the elementary principles of the oracles of God, and you have come to need milk and not solid food. 13 For everyone who partakes only of milk is not accustomed to the word of righteousness, for he is an infant. 14 But solid food is for the mature, who because of practice have their senses trained to discern good and evil.
