We hear your cry for your precious daughter and we stand with you in deep concern and prayer for her protection and healing. Children are a sacred trust from the Lord and we know your heart is grieved to see her suffer so severely and repeatedly while in her mother's care.
Behold, children are a heritage of Yahweh. The fruit of the womb is his reward. Psalm 127:3 We take seriously what you have observed with the high fevers, bacterial infection and the sour foreign odor in her tumbler, and the pattern you describe of her becoming extremely ill suddenly under her mother's care. If harm is being intentionally caused to a child, that is a grave evil in the sight of God. Jesus said, but whoever causes one of these little ones who believe in me to stumble, it would be better for him that a huge millstone should be hung around his neck, and that he should be sunk in the depths of the sea. Matthew 18:6 The Lord sees what is done in secret and He is the defender of the vulnerable. Defend the weak, the poor, and the fatherless. Maintain the rights of the poor and oppressed. Rescue the weak and needy. Deliver them out of the hand of the wicked. Psalm 82:3-4
We also hear your description of her mother as extremely mean, nasty, malicious and evil. We rebuke any malice, cruelty and harm directed toward this little one. Such actions do not align with God's will and must be confronted in truth and righteousness. At the same time we must leave vengeance to the Lord while we do what is right to protect. Don't seek revenge yourselves, beloved, but give place to God's wrath. For it is written, Vengeance belongs to me; I will repay, says the Lord. Romans 12:19 That does not mean we remain passive. God has established authorities for the protection of the innocent and we are to use them. For he is a servant of God to you for good. But if you do that which is evil, be afraid, for he doesn't bear the sword in vain. Romans 13:4
We urge you in love to take immediate and wise practical steps while we pray. Continue to seek prompt medical treatment and keep every medical record, diagnosis, prescription and doctor's note. Document dates, symptoms, photographs if appropriate, and keep the tumbler and any other items as evidence without altering them, and show them to her pediatrician. Seek godly counsel and legal counsel right away, and report your concerns to the proper authorities for child welfare and to law enforcement if you believe she is being intentionally harmed, so that a proper investigation can be made. Bring your pastor or a trusted mature believer alongside you for support and witness. If any of you lacks wisdom, let him ask of God, who gives to all liberally and without reproach; and it will be given to him. James 1:5 We also encourage you to pray for discernment to speak only what is true and to not bear false witness, while still acting decisively to shield your daughter.
We pray together for your daughter and for you and even for her mother that God would bring truth to light and bring justice and mercy according to His perfect will.
Heavenly Father, we come before You together in the name of Jesus Christ, for there is no other name by which we have access to You and no other name by which we are saved. We lift up this precious little girl to You. Lord, You see her body and You know every fever and infection and every cause. We ask for Your healing hand upon her, restore her health completely and protect her from further harm. He who dwells in the secret place of the Most High will rest in the shadow of the Almighty. I will say of Yahweh, He is my refuge and my fortress; my God, in whom I trust. Psalm 91:1-2 Be her refuge and fortress, surround her with Your angels and let no weapon formed against her prosper. Give her father wisdom, strength, courage and favor as he seeks medical care, documents what is happening and seeks help from the authorities You have ordained. Guide every doctor, nurse and official involved to act with clarity and integrity. Expose any evil that is being done in secret and bring it into the light, and we pray that her mother, if she is causing harm, would be convicted of sin, rebuked by Your Spirit and brought to repentance, and if she will not repent, that You would restrain her hand and bring righteous justice to protect this child. Help this father to be a godly father who raises his daughter in Your nurture and admonition with patience and love, and to cast all his anxiety on You because You care for him. 1 Peter 5:7 We ask all of this in the mighty and merciful name of Jesus Christ, our Lord and Savior, Amen.
