A Paduan: You say:
1- "They ( Ananias and Sapphira ) lied to the Holy Spirit." Then you ask: "Why do you say that they didn't obey Jesus absolutely?" Isn't 'lying to the Holy Spirit' a case of not obeying Jesus absolutely? Can a Christian be regarded as obeying Jesus absolutely if he 'lies to the Holy Spirit'?
2 -"They ( Ananias and Sapphira )...died...could have been cardiac arrest." Double, fatal heart attack? Really? At Acts 5:9,10 Peter says to Sapphira: "Behold the feet of them which have buried thy husband are at the door, and SHALL carry thee out. THEN fell she down straightway at his feet....dead." According to this, Peter KNEW IN ADVANCE that she would die. If she died of cardiac arrest, how would Peter have known IN ADVANCE that that would happen to her? The implication of this story is that Peter was somehow informed by heaven that heaven was about to execute her.
3 - "Maybe they died SPIRITUALLY." It couldn't have been that because verse 10 says that she was: "BURIED" alondside her husband. Are SPIRITUALLY dead people buried?
4 - "They themselves ( men )" mete out the "everlasting punishment" foretold at Matthew 25:41,46. Really? Who is foretold as having this role at 2 Thessalonains 1:7-9?: "...The LORD JESUS shall be revealed from heaven with his mighty angels, in flaming fire, taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: Who shall be punished with EVERLASTING DESTRUCTION from the presence of the Lord, and from the glory of his power." Clearly, Jesus is portrayed as the great heavenly executioner. This passage predicts that he will inflict, "everlasting destruction" on "them that know not God, and that obey not the gospel of our Lord Jesus." That doesn't sound too 'friendly' to me.
