Yes we all lie from time to time. I understand the other views here on this story, but I believe the Bible. I believe that it is God's word to us. So my reasoning on this story is this:
These people were living for God and Annias and Sapphira were supposedly part of this but in their heart they were not. The idea was to share with God's people for the development of a church. Greed took them over and they wanted to be more than just a regular person within this "church". They were self pleasing. While we all have this in us at times, how many of us have actually done this in the face of God? Now I am different than most of you, I have never been a JW and never believed their lies. So some of you may think that you have lied to God's org or something of that nature, but what have you kept from God? The org is not God's org!
That is what I get from this story, we do lie to each other, we do hide things from each other, but Annias and Sapphira were lying to God in their hearts, not to Peter or the others. The people would never know (well maybe but probably not) but the group did this for God and Annias and Sapphria knew that it was for God.
Take it or leave it, but that is how I see it.
