What is the believer's body according to 1 Corinthians 3?

Les explains that every believer, the moment he believes, the Spirit comes and indwells. This body is the temple of the indwelling Holy Spirit. He illustrates that when you go to some ungodly place, you cannot check God at the door; you take Him wherever you go, so you better be careful where you go. The context quotes, 'Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you?' Les notes this is plain language, not requiring a theologian. He connects it to the third person of the Trinity—God the Father, God the Son, and God the Spirit—coming to indwell the believer. That is why God can know every thought, every place, and everything we do, because He is here. Les also compares it to Solomon's temple in Jerusalem, where the presence of God in the Shekinah glory came down and dwelt. That was a foreview of this age of grace, where when God saves an individual, the individual becomes a temple, a dwelling place, and just as the Shekinah glory came into Solomon's temple, the Holy Spirit comes into us.
