In marriage we should be able to rest secure in the commitment of our spouse and not pursue the other as an idol. In cohabitation you are continually on audition to be the other’s choice. That insecurity makes it difficult to pursue God wholeheartedly, especially as God asks you to be iron—and to be iron for each other.
God encourages us to remain pure until marriage, but you may come across a young adult who has already been sexually active. Here is the good news—God is a redeemer, knew we would mess up, and made our brains moldable.
There is so much in our culture that is untrue about sex. God has given us a beautiful gift in our sexuality, and we need to talk about how He does want us to use this gift.
