I think that God has the ultimate plan in everything we do...even the smallest decisions we make. Our ability to stand tests and trials and being able to overcome physical things is our training on earth. It is my opinion that how we do here will determine what level we will be on, in heaven. I believe that everyone has a calling, duty and important role God has for everyone, here and in heaven. So we won't be able to change, what we have done on earth determined that. We will all have a role and a special job, so we will be doing something and that will be determined by God. We need to try to be the best we can spiritually here, in practice for our life in God's kingdom to come soon.
You may want to pray for God to reveal the answer to you and he will if your heart is true. I can only offer what I think.. Blessings to you.
