'Within' in the Bible

For, among human beings, who knows a man's inner thoughts except the man's own spirit within him? In the same way, also, only God's Spirit is acquainted with God's inner thoughts.

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

For what business of mine is it to judge outsiders? Is it not for you to judge those who are within the Church

Or do you not know that your bodies are a sanctuary of the Holy Spirit who is within you--the Spirit whom you have from God?
