Hi, I don't know if this will help or not, but it is normal for people to have those feelings and thoughts inn this kind of circumstance. What makes it a sin is if a person followed through on these fantasys/feelings. [1 corinthians 10:13] "No temptation has seized you except what if common to man. And God is faithful' he will not let you be tempted beyonnnd what you can bear. But when you are tempted, he will also provide a way out so that you can stand up under it." [luke 22:46] "Why are you sleeping?" he asked them. "Get up and pray so that you will not fall into temptation." I think the best things you can do for this is to pray,pray,pray. In the morning, surinnng the temptation, at night, just any time. Then, to remove yourself from situations where you might be tempted most.
Father, I thank you for this new day, where we have the opportunity to start over with a clean slate. I thank you Lord God for the forgiveness that comes with repentance and prayer. Lord, I lift up this couple to your tender loveing care and ask that you would forgive them where they need forgiveness. Father I pray with all my heart that you would help this couple to overcome the temptations facing them, that they may keep themselves holy and pure until the day that you ,Lord, bring them together as man and wife. Lord I ask that your will be done in this relationship, and that if they are meant to be together you will draw them closer to you and to each other during this time. Strengthen them Father and give them the courage and comfort that is needed to hang in there for you. Father I pray that you would bless these two in their journey through life, and that you would always guard their hearts, and lead them in the direction you would have them to go. Lord, I ask that you wuld comfort them when things get tough, and remind them of the beauty of your love and the awesome ness they will one day share together as children of God.
Father, I thank you and praise you for all that you are doing and going to do in the lives of these two dear children. In the precious and holy name of Jesus Amen
God bless you both and when things get really tough, find some one to talk to who can also encourage you. Remember Prayer always and THE BEST OF LUCK TO YOU BOTH!
