'Within' in the Bible

For who among men knows the things of a man except the man's spirit within him? So too, no one knows the things of God except the Spirit of God.

Do you not know that you are God's Sanctuary, and that the Spirit of God has His home within you?

For what have I to do to judge them also that are without? do not ye judge them that are within?

Do you not know that your body is a temple of the Holy Spirit who is within you, whom you have [received as a gift] from God, and that you are not your own [property]?

to those without law, as without law -- (not being without law to God, but within law to Christ) -- that I might gain those without law;

For if I pray in a tongue, my spirit prays, but my mind is unproductive [because it does not understand what my spirit is praying].

Then what am I to do? I will pray with the spirit [by the Holy Spirit that is within me] and I will pray with the mind [using words I understand]; I will sing with the spirit [by the Holy Spirit that is within me] and I will sing with the mind [using words I understand].
