The word "discipline" is a loaded word. For some it can sound negative, punitive or even harsh. But within the context of a life of faith, the author Hebrews wants us to see that discipline isn't something to fear, rather, it's essential to our growth and maturity as followers of Jesus! Hebrews doesn't describe discipline as solely punitive, but as formative. And so discipline isn't evidence that something has gone wrong in your relationship with God - it's evidence that you belong to him and are being shaped more into his likeness.
