Useful in identifiable and unidentifiable ways

“God has breathed life into all of Scripture. It is useful for teaching us what is true. It is useful for correcting our mistakes. It is useful for making our lives whole again. It is useful for training us to do what is right.” (2 Timothy 3:15-16, NIrV)

Implication: Scripture is useful for these things even when we can’t identify how it is useful for these things. God uses the word, by the Spirit, to wash us, in known and unknown ways.
