Notice it says that marriage is involved to bring forth fruit unto God. And Marriage means a God-ordained union and relationship. People are thinking they are joining the church and producing themselves plastic fruit and dolls and thinking they are providing God with fruit and a Bride for Christ. Birth is a miracle. It requires a relationship between man and woman.
People have a form of godliness but deny the power thereof.
You have to have a relationship with Jesus to draw power and produce godliness. This is not a worker's instruction class. We are here to enhance our relationships with the Lord. We are here to tell people about what this is all about, that they for the first time might come and reach out to Him by faith and experience the miracle of having a relationship with Him that they might be baptized into His death and made part of the natural resource that God is using to make the Bride. There are species in this world.
