My heart is that God's children will grasp for purity in their lives. Not just in the area of emotional purity, but physical, their thoughts, actions, and any other aspect of their life.
Do I think emotional purity is a salvation issue? Of course not! I do not believe that you have to be emotionally pure to be saved. I do however believe that finding and maintaining emotional purity, as well as other areas of purity in your life, will lead to peace, joy, and a guilt free conscience.
God desire is for us to find purity. Even as a married woman I am called to be pure in many areas of my life. It doesn't end once your married, but takes on a new meaning. For me purity is in how I treat those around me, how I present myself, what I think about, how I treat my husband and remain emotionally faithful to him.
Blessed are the pure in heart for they shall see God. Matt 5:8
