Apparently Ananias was speechless, and Peter finished with this condemnation: "You have not lied to men but to God." And just how did Ananias lie to God?
In Acts 4:31 we are told: "And when they had prayed, the place in which they were gathered together was shaken; and they were all filled with the Holy Spirit."
So, the church was sustained by the inspiration and motivation of the Spirit of God and the deception of Ananias and Sapphira was a violation, not only of the community of God but also of the will of God.
There is a certain irony in their names: Ananias means "God is gracious" and Sapphira means "beautiful."
Regrettably, they did not live up to their names.
It is not difficult for me to surmise that these two died instantly because all too lately they recognized the enormity of their betrayal.
They had acted as if God were powerless or even nonexistent – just as some of us do from time to time. While we would never say, "There is no God!" we might act as if God does not exist, see or care.
As I have already noted, some people conclude Ananias and Sapphira were punished by God, not because they held back some of their wealth but that they willfully pretended they had given their all. Those of us who make an annual pledge of contributions to our church result may tremble at that thought.
But, if so, how would this be in harmony with and support of the example of Jesus himself, who cursed no one from his cross and promised eternity to the thief crucified next to him? Luke tells us "great fear came upon the whole church, and upon all who heard of these things" (5:11).
That is understandable, but while it might have been primary in the Old Testament, "fear" is not the basis of the Good News of Jesus Christ.
