And, dare I say, sex as God designed it is so much more than what Samantha was taught.
But there's something more subtle at work here than the obvious inequality Samantha claims she was taught. She says she was taught to remain pure "for him". Really, really wrong motivation! What if there is no future husband? Does that mean all our "saving ourselves" is for nothing? More on this later.
For my part, I ask for God's strength and grace to be pure in my thoughts and actions, not in order to have a great marriage, earn God's favor, or gain anything at all.... but rather because obedience is God's love language!
I can only love Him, because He first loved me. There truly is nothing sweeter than walking closely with Him--not even extra-marital sex or other habits of the mind and eyes that will ultimately harm me and grieve my Creator, who I delight to honor.
That said, am I pure? Well, purity is not a box to check or a line we either have crossed or not--it's a lifestyle of submission to Christ, who alone can keep us pure. Without Him, even if we don't check that box or cross that line, we are powerless against the sins of the mind. Jesus said if we even look at another to lust after them, we have already committed adultery with them in our hearts. God, help us! (And, He does!)
Grace and peace to you.
