Desire To Conceive, Fulfillment Over Barrenness
Father, we thank You that children are the heritage of the Lord, and the fruit of the womb is His reward . Children are Your idea, Father; You thought up children, and family, and home. You instituted the family in the Garden of Eden. You ordered children; You commanded them when You said to Adam and Eve, "Be fruitful and multiply." You said that the barren womb is never satisfied. Lord, the Word declares that I am wonderfully and fearfully made by You; therefore, I'm perfect and able to conceive and have children. You said that I/my wife would be a fruitful vine by the side of our house and our children like olive plants around our table We are not ashamed but happy because our quiver is full of children (or arrows, as You call them).
Thank you, Father, that You designed and fashioned me/her, to have children, that in the Bible bareness was the exception, not the rule, not Your will, not normal, something against Your plan and purpose. And in Your goodness and faithfulness every barren woman in the Bible who was godly and believed Your Word became pregnant; You opened her womb and bless her, and she gave birth to a precious baby just as I/she will. You make the barren woman to keep house and to be a joyful mother of children.
You said, Father, that because You are our God and we are Your people and have a covenant with You that You will love us and bless us and multiply us and bless the fruit of my/her womb and that neither male nor female among Your people would be barren.
Father, we are redeemed from the curse of the Law by Jesus, and being barren is under the curse of the Law; therefore, we will receive from Your grace and have children.
Father, no plague, no evil shall come nigh our dwelling. We are healed by the stripes of Jesus. Sickness of any kind is taken out of our midst. You said to ask anything of You in Jesus' name and it would be done; and that if two of us on either agree as touching anything it would be done. So we pray and we agree with You and Your Word, Father, that we will conceive and bring forth a healthy, precious baby to Your glory and honor. We pray all this according to Your Word and will. You said, This is the confidence that we have in You, that if we ask anything according to Your will, You hear us; and if You hear us, we know we have the petition we desire of You, We have it now. Thank, Father, in Jesus' name.
Now, talk to your body :
Bodies, we speak to you in Jesus' name; You will come in line and agreement with the Word of God. You will respond to His holy Word. You will function properly and perfectly, the way God intended you to. Every part, every organ of our reproductive system conforms to the Word and plan of God as we come together in pure, martial love. Body, conceive! Be pregnant. Cooperate with God's plan; perfect ovulation, release of perfect eggs from the ovaries, through the fallopian tubes, penetrated and impregnated, fertilized by healthy sperm. Good solid attachment to uterine wall and nourished and protected for nine months (40 weeks) unharmed and unhindered. Grow to a perfect baby - spirit, soul, and body. Your Word says, Father, that none shall cast their young, nor be barren amount Your people and the number of our days You will fulfill. This pregnancy will be fulfilled. We decree it in Jesus' name and receive God's best; we won't settle for anything less in Jesus' holy name. Thank You, Lord, that it is so and done to Your honor and Glory. Amen.
Saint Gerard (Patron saint of motherhood)
O good Saint Gerard, powerful intercessor before God and Wonderworker of our day, I call upon thee and seek thy aid. Thou who on earth didst always fulfill God’s designs, help me to do the holy Will of God. Beseech the Master of Life, from Whom all paternity proceedeth, to render me fruitful in offspring, that I may raise up children to God in this life and heirs to the Kingdom of His Glory in the world to come. Amen.
After your first positive pregnacy test say this one.
O great Saint Gerard, beloved servant of Jesus Christ, perfect imitator of your meek and humble Savior, and devoted child of Mother of God, enkindle within my heart one spark of that heavenly fire of charity which glowed in your heart and made you an angel of love. O glorious Saint Gerard, because when falsely accused of crime, you did bear, like your Divine Master, without murmur or complaint, the calumnies of wicked men, you have been raised up by God as the patron and protector of expectant mothers. Preserve me from danger and from the excessive pains accompanying childbirth, and shield the child which I now carry, that it may see the light of day and receive the purifying and life-giving waters of baptism through Jesus Christ our Lord. Amen.
Good luck and may God bless you all with children!
