There are people in the millennial kingdom of God who are being buried or cremated by friends and family because they have refused to do what God has commanded them to do. You cannot claim to be a beneficiary of God's promises unless you are willing to be obedient to every command of the indwelling Holy Spirit Of God. If you struggle with unbelief, ask God to help you to overcome your unbelief, then begin by following these five commands that have been given to every person in God's millennial kingdom.
First, cancel and shred every cremation order and every burial plan that you have ever executed, and try to avoid visiting doctors and hospitals. Second, ask the Holy Spirit Of God to teach you how to pray in the language of the Spirit so that you always can communicate with God in every emergency situation. Third, train your spirit to communicate with God every morning and every evening in the language of the Spirit so that he always knows your circumstances, as well as anything that the devil may have been planning for you.
Fourth, tell the Lord God Almighty, in the language of the Spirit, how you would like to deal with any difficult circumstances you might be encountering, including health challenges, and ask him to do only what is best for you, for others, and for the kingdom of God. Fifth, command your spirit (in the language of the Spirit) to do and to obey only what the Holy Spirit Of God commands, so that your spirit can never be commandeered by Satan in order to accomplish his evil purposes.
