No matter who is around, our sins will be found
out.  Even if we “get away with it”, God
knows, and we will be called to account for what we do.  We are saved by grace, but that doesn’t mean
we don’t need to ask for forgiveness and repent.  Moses ran. 
How often do you find yourself running from God when you just don’t want
to face what you’ve done?  I know I have
done so in the past and it never pays. 
It just draws it out and makes it much more difficult to face
later.  
Ask God to forgive you for things that are
coming between you and God.  Don’t let
your relationship with Him suffer because you don’t want to face the
truth.  He is truly a loving and
forgiving God and He already knows about it, so no use trying to pretend.
