Lori, God won't bless you as you make a sinful decision. If you're living with and having sex with a man who's not your husband, God will remove his blessing from you and allow you to face the consequences. Christians who pray in agreement with you to act in sin have to face judgement as well.
Heavenly Father, I come before you and ask that you please convict Lori's heart so that she will repent and commit her life to you. Bless her to submit her desires to you so that they come into alignment with your will. In the Name of Jesus Christ I ask that you would make this relationship so uncomfortable for the two of them that they have no choice but to repent of it, and lay it at your feet. I ask that you give Lori and the boyfriend courage to stand up and do what's right in God's eyes, not man's. Lord, I decree and declare Lori's womb be closed until she submits her desire for a child to God. Children are gift from the Lord, and need to be brought up in the way and admonition of the Lord. If Jesus is her Messiah, please reveal yourself to her right now. Rain down the Holy Spirit to convict like a downpour in the drought-stricken desert. I praise you Lord for giving us the Holy Spirit which is useful for teaching, for reproof, for conviction, for comfort and for healing. Please help these two to experience your unfailing love in such a way that they won't settle for an uncommitted relationship. I praise you Heavenly Father because you know my name, and answer my prayers. Amen
