Dear Sue,
Once we are on the other side (heaven) we will have a different jobs to do. Not because we will have to but because we’ll enjoy it. Your father although on the other side, still like to do a spiritual work which brings blessings to you and others. Everything of course according to God’s will. He will be close to you and your family as long as the need will be there. There is no need to reject his help it could bring only blessings. We know all the saints in heaven intercede for us in our struggle.
