The axolotl (pronounced ACK suh LAH tuhl) is a biological enigma. Instead of maturing into adult form, this endangered Mexican salamander retains tadpole-like characteristics throughout its life. Writers and philosophers have used the axolotl as a symbol of someone who fears growth.
In Hebrews 5 we learn about Christians who were avoiding healthy growth, remaining content with spiritual “milk” intended for new believers. Perhaps because of fear of persecution, they weren’t growing in the kind of faithfulness to Christ that would enable them to be strong enough to suffer with Him for the sake of others (vv. 7-10). Instead they were in danger of sliding backward from the Christlike attitudes they had already shown (6:9-11). They weren’t ready for a solid diet of self-sacrifice (5:14). So the author wrote, “We have much to say about this, but it is hard to make it clear to you because you no longer try to understand” (v. 11).
Axolotls follow the natural pattern set for them by their Creator. But followers of Christ are designed to grow into spiritual maturity. As we do, we discover that growing up in Him involves more than our own peace and joy. Growth in His likeness honors God as we unselfishly encourage others.
