2 Like newborn babies, crave pure spiritual milk, so that by it you may grow up in your salvation, 3 now that you have tasted that the Lord is good.
1 Peter 2:2-3
Is Peter telling these believers they are like babies? In a sense, yes.
The pure spiritual milk is the stuff that makes us grow: faith, obedience, patience, love, faithfulness. Essentially, it’s the basic tenets of the faith.
The story goes of famed Green Bay Packers coach Vince Lombardi. At the beginning of training camp, he’d start out with “This is a football.” And from there, the team would work on the basics of the game of football. If they couldn’t do the very basics, why would he want them to go further in their training?
Similarly, Peter is merely stating that returning to the basics is never wrong. It’s where we grow strong and solid in our faith.
Often we overcomplicate our faith and get into trouble. The problem is, most of the time we don’t master the basics but want to move into advanced theological doctrines that have little to no bearing on everyday faith.
Stick to the basics, Peter is telling us.
