Ananias and Sapphira [to quote you] "were hypocrites who held God in contempt. They had no concept of His power, that He is able to see what people do in secret and reveal it to others. They were exposed as unbelievers who had no fear of God."
Thus, such terrible and miserable people are put to death immediately. I am with you this far. So liars who hold God in contempt are put to death irregardless of the Jesus' sacrifice to redeem everyone else. Got it.
However, now I'm no longer with you. Why are murderers and persecutors of Christians, God's new chosen People rewarded? Enter Saul of Tarsus who [to now paraphrase you] "was a hypocrite who held God in contempt. He had no concept of His power, that He is able to see what people do in secret and reveal it to others. He was exposed as an unbeliever who had no fear of God."
If liars are killed without mercy, then murders killing Christians certainly would be too. No, I'm wrong again. Saul gets a miracle on the road to Damascus, he is not held accountable by God for any of the murders he committed against these Christians, and finally he gets to write many books of the New Testament.
Liars are worse than murderers by this comparison post crucifixion. Liars are put to death without mercy and given no time to redeem themselves. Murderers not only get a second chance, they are greatly rewarded by God. Another astounding biblical inconsistency, IMO.
