For every “no” that a Christian says, there is a much bigger “yes”.
Let me give you an example: Christians say no to pornography. They say no to it because it is sinful to look at anyone lustfully. We know that from the Ten Commandments, which tells us not to worship an image, or to commit adultery, porn is designed to elicit those two things in the viewer, worship of the image, and lust over the person in the image.
So, that is a very clear example of something which is stuff (porn), and we say no to it.
What is the much bigger yes? The much bigger yes is marriage. It is marriage to Christ first and foremost. A marriage to Christ means that there is so much more pleasure to be found in prayer than in porn.
Then there is human marriage, which teaches us about our marriage with Christ, whether we ourselves are involved in that marriage or not, whether we are single or married. The very existence of marriage on this earth is a good thing that we must all encourage.
If we are single, we involve ourselves in encouraging married couples and helping them stay married whilst continuing to enjoy the main marriage, which is Christ and the church.
If we are married, we dedicate ourselves to our spouses and say a much bigger yes to all the good stuff of marriage: to sex, holding hands, talking together, romantic dinners, laughing together, playing games together, raising children together, and having children if the Lord grants children to us, and everything else that comes with marriage—making a home and helping each other in our work.
Every no has behind it a much bigger yes.
And we need to repent of the times where we have made Christianity much more of a no religion than a yes religion because everything God created is good. There is not one thing that God created that is not good.
