2 Corinthians 5

So we are always confident, knowing that while we are at home in the body we are absent from the Lord.  For we walk by faith, not by sight. vv.6-7

Read chapter 5
I remember the first time I had someone explain to me the first part of this chapter about our what this earthly tent is as I was at a wedding reception sitting next to a Bible Teacher I'd never met before.  Many make the mistake of saying the earthly tent is our body, but as this Bible teacher explained to me the Greek word and context, it clearly showed otherwise.  Here is a clip of an article he wrote on it:

This verse is translated in a misleading way in the New King James Version, which I have quoted here. The Greek word that is translated “at home,” as well as the word that is translated “absent,” are words that occur only in this passage and in no others in the Greek Bible. They are the words endemeo and ekdemeo in Greek. Central to these words is the stem dem, which we use in words like democracy, demographics, or epidemic. This root comes from the Greek demos, which means “the people.” The Greek “en” means “in” or “among,” and “ek” means “out of” or “away from.” Therefore, endemeo means “to be among one’s own people,” and ekdemeo means “to be away from one’s own people.” Therefore, the thrust of II Corinthians 5:6 is,
“And so we are confident at all times, perceiving that while we are among our own people in reality, we are away from our own people from the Lord.”
This idea, that a prophet could speak against his own people as if he were not one of them, runs all the way through the Bible, though it is not explained in detail elsewhere as it is here. Paul was a Jew and a loyal one, but from the Lord he was given the position of acting like he was not one of them at all so that he could entreat them or condemn them as from God, not from among themselves.

Both believers during the time of the Acts period when miracles were obvious and today when they're not so obvious, had and have to choose to walk by faith and not by sight. Even among other believers we have to choose not just what we see them do but confidence in what God says to do.  Today, how can you choose to walk by faith and not by sight?
