Family, life and love make for eternal memories to talk about on the other side. 1 Corinthians 15:14 - "If Christ has not been raised, our preaching is useless and so is your faith." But Jesus "IS" risen alive and well along with all who have trusted in Him and gone on before us, now awaiting our arrival into His presence on the other side of death. Keep the faith bro. You have so much more to do with your dad in a far better world yet to come.
