For the world is becoming full of impostors—men who will not admit that Jesus the Christ really became man. Now this is the very spirit of deceit and is anti-Christ. Take care of yourselves; don’t throw away all the labour that has been spent on you, but persevere till God gives you your reward. (2 John 1:7,8)
In the Greek, that last sentence is interesting because, right in the middle, John changes the voice from 1st Person Plural - "The things we have accomplished" - to the 2nd Person Plural - "a full reward you all might receive." And that's one of the things that I find so remarkable about being part of the Family of God: that we together are accomplishing the work of the Kingdom in this generation, and yet that I, that you, are each individually getting to personally soak up all the rewards on offer.
And why does this matter? Because our collective-yet-individual, subjective, personal experience of Him turns the words of verse 7 on their head:
“For the world will become full of truth-tellers – men and women who will prove that Jesus the Christ really became man. Now this is the very spirit of truth and is pro-Christ.”
How absolutely wonderful that our lives may prove the truth of His life!
