I cannot disagree with you, you are correct...but only if we are 100% inline with God's will and in tune with The Holy Spirit....which is not always the case and hence we are required to use our logical minds to apply logical as ''Christian as possible'' guidelines to these types of situations should God not intervene.
As a precedent for God and preachers to set, not to kill is good just as we should pray for everyone without doubt that they will get healed.
The practical solutions are:
Re healing: If your kids are sick, pray for them to get healed, if God doesnt heal them after 1 prayer (God is not deaf), take them to the hospital. (In the meantime try fasting and praying to get more inline with God's will / in the spirit)
Re War: Pray for Saddam that God changes his heart. If God deosnt, remove him from power asap, before he hurts anyone else.
Re a rapist caught in the act: Pray immediately (like 2 seconds) for God to intervene and take vengeance, if God doesnt, do what you can to stop him...even if it means killing him.
Conclusion:
Jesus healed everyone He prayed for because He was in the perfect will of God / He walked 100% with the Holy Spirit...Jesus could call 1000 angels to take out an evil dictator....we can to...but not as often (if ever) as Jesus...as we ARE NOT always (if ever
)100% in the spirit and alighned with God's will...hence
Christian common sense is required...God gave us a brain....and Christians should have the ''clearest'' thinking logical minds...hence why Paul says if anyone should make laws it is us.
