Well I don't have any children yet, but Lord knows it one of the most awited events in my life. I coulnd not imagen having to indure three miscarriages. I am so sorry for your pain.
I pary that in the name of Jesus every and all parts of both your spouses and your body will aline themselves to divne portocal. That your were both made in the image of the triune God perfect and complete. That although you were born into the sin nature as beleivers in Christ all of yours sicknesses or imperfections were nailed to the cross. That his precious blood was shed not just for are sins, but also that by his strips we have been healed. I declare that whatsoever has been malfuctioning in your body will become corrected allowing not just for the birth of a child, but the birth of as many children that you so desire. And that the pregnacy and birth of all your children from here on out shall be smooth and with defect, painless as possiable in the mighty and awsome name of Jesus Christ I pray Amen!
Glory to God it will happen!
