Why has Christianity lost its power according to Les Feldick?
Christianity has lost its power because separation from unbelievers is no longer taught or practiced. The average person sees no difference between the average Christian and the average person of the world. God intends believers to be separated from the world as He separated Israel from Egypt, so the world knows where they stand.
Les teaches that Christianity has lost its power because separation from unbelievers is no longer emphasized. He points to 2 Corinthians 6:14, where Paul says, 'Be ye not unequally yoked together with unbelievers.' Les notes we don't hear much about separation anymore. The average person can't see any difference between the average Christian and the average person of the world, but God didn't intend it that way. Just as He separated Israel from Egypt, He wants to separate believers from the world. Les clarifies this does not mean being oddballs or constantly asking for persecution by our actions, but the world should know where we stand. Verse 15 asks what relationship a believer has with an infidel, reinforcing that we have to be separated all the way through.
