The structure of the Blog Post is an automated system you don’t have to arrange your post whatever Post you wrote will pop at the top of the posts list with date and time. What you might do is copy all your posts and save theme somewhere and then delete all these posts from your Blog and then taking them back according to the way you intend your lists to be which one you like em first or last. Put in mind the first post you published will be the last one in the list.
Thanks for the response. I also kept reading and found I could simply change the date of the post which reorders! A much simpler way.
Keep published date for its own purpose, unless date is insignificant for your content.
Use this plugin for ordering posts manually.
