why we've grouped some questions around definitions?

Many today are caught up with attempting to give Bible definitions in terms of man’s definitions. They may use a dictionary, or go to the original Hebrew/Greek, and this can be helpful along with looking at how various Bible translations have handled it. But Paul makes it clear in 1 Corinthians 2:12-13 that Bible definitions belong to God, and God alone:

“Now we have received not the spirit of the world, but the Spirit who is from God, that we might understand the things freely given us by God. And we impart this in words not taught by human wisdom but taught by the Spirit, interpreting spiritual truths to those who are spiritual.”

There may be no better application and example for how Scripture interprets Scripture than in providing Bible definitions.
