Bobby - May God bless you with the knowledge to be one of his Elect.
I hope I can help with some of the answers you've posted... Not sure how much detail to go into...
1. When our physical bodies die do we instantly go to be with Father?
Answer: Yes, as Tray also quotes - Ecclesiastes 12:6-7 states 6-Or ever the silver cord be loosed, or the golden bowl be broken, or the pitcher
be broken at the fountain, or the wheel broken at the cistern. 7-Then shall the dust return to the earth as it was: and the spirit shall return
unto God who gave it.
Also - Christ is the LORD of the living, not the dead. And as you stated 2Cor 5:8 - We are confident, [I say], and willing rather to be absent from the body, and to
be present with the Lord.
2. If you understand God's purpose for his children, understanding that Satan himself came down bodily and impregnated Eve begetting Cain, If you know that Satan will come disguised as Christ to deceive the whole world into believing he is Christ, and that you understand most importantly that you must not deny the Holy Spirit to speak through you when you stand before Satan. If you understand all these things the Yes you are one of God's Elect. I cannot stress enough the importance of my last point - make sure whatever you do, do not prevent the Holy Spirit to speak through you - doing so will make you subject to the second death - the death of the flesh everyone goes through - for those that deny Christ / Holy Spirit will not be written in the Book of Life.
3. That's the Rapture Theory - God's Elect will be here "Working for God" ready to stand before Satan to allow the Holy Spirit to speak through you. The Rapture is just a ploy that Satan created to get people to not study the Bible. Anyone that is fooled into believing the Rapture Theory WILL be deceived by Satan thinking he will Rapture them away.
You need to pray to our Father in heaven for the latter rain to fall on your mind to help you grow in His Holy Word.
Take care and may God Bless you...
