My dear brother Stephen, I pray that you will be given the faith to trust in god fro great miracles including resurrection from the dead. But I DO NOT THINK YOU REALIZE WHAT YOU ARE ASKING FOR! For I believe that god answers all prayers of true believers and Christians, and with a prayer as big as this,I hope you realize that God probably won't answer this prayer by letting you see some random guy on the street get killed and then ressurected by someone else for you to be a witness to a miracle you might not have believed in. Much more likely (and I say this from experience) God will most likely someone close to you to die unexpectedly, and YOUR FAITH will be what is needed to bring them back to life, not somebody Else's. I once asked god to give me faith in him because I had none, and soon after, my body broke out in a rash that is very severe and unsightly today, so instead of God just anwering me with an easy and convenient way for me by simply filling my soul with faith, God gave me a reason to have faith in him - faith that this rash will one day be fully healed and cured simply because His word tells me so, Likewise, instead of God simply showing you someone being resurrect from the dead, god will most likely give you a reason for someone to be brought back from the dead, and that's YOUR FAITH being needed to bring a loved one gone to soon, not merely witnessing some stranger resurrect another stranger by faith in Christ. Think about it, why should somebody else lose a love one for however temporary a time just so your prayer can come true, the prayer would not be for them to receive but for you to receive? Also, even in scripture when Jesus resurrected the dead himself, Lazurus was dead for FOUR DAYS before being resurrected, and a little girl was dead for hours before she was resurrected, and Jesus was not resurrected until 3 DAYS later (Books of Acts and John), indicating that much faith would be needed on your part for a loved one to be resurrected. So ask yourself, do you think you would show God faith for healing a dead loved one even if they were gone for several days before being resurrected. I am not asking you to ask god to take back your prayer, I am merely asking you to better evaluate it.
I hope that you will take to heart my response and that it did not offend you. I would love for a reply back to me to hear your say on the matter. Regardless, God bless you.
