Who's standard are you living up to? Do you expect others to live up to your standard?
One thing I love about God is that He calls us each to different things, He convicts us at different times and of different things, and He brings unique situations into our life.
One thing God has taught me is to not place my convictions about non-essential issues onto other people. God's called me to live my life in such a way, but He may not call someone else to live their life the same way (How boring would it be if we all did the same thing anyway!?)
I realized that I am not the Holy Spirit and I've tried to take all the "you should" and "do this" phrases out of my vocabulary. (Except for my kids, in which I have the God given responsibility to train them and guide them until they are able to hear from God on their own.)
There's not list in how to remain emotionally pure before or after marriage. There's no "do this" and you'll be pure! It's a matter of your heart and the standard God calls you to may look totally different than me or those around you!
