Sorry this must be short, but wanted to put some scripture to answer Ron's question.

Jude 1:24
Now [u]unto him that is able to keep you from falling, and to present [you] faultless[/u] before the presence of his glory with exceeding joy,

Jude 1:21

There are many more do s and don'ts which are attached to 'yourselves', if you search for them. It's an interesting list. :-)
