When someone dies, if they are eligible for entrance into heaven, their transition into heaven is immediate and seamless. If they are not eligible for entrance into heaven, their spirit remains on the earth until hell claims it. In the past, hell eagerly snatched the spirits of the deceased, sometimes within hours of their passing. That can no longer happen. The Lord God Almighty has determined that if they are not eligible to be accepted into heaven, their spirit will have a seven-day grace period on the earth before hell can claim them.
If you have a friend or relative who has just passed, you have God's authority to contact them through the spirit realm within the seven-day grace period to determine whether or not they are safely in heaven. Ask them where they are and what they see. If they are sitting in front of an open door to hell, it means that hell will soon be their destination. From hell's perspective, if they do not have the mark of the indwelling Holy Spirit of God, the finders can be keepers. If you care about them, you have seven days within which to give them the indwelling Holy Spirit of God. That act of goodwill will mark them as people belonging to God, and will instantly catapult them into the third heaven, out of the reach of hell and Satan.
