We understand your concern and are here to stand with you in prayer and truth. Firstly, let's address your request and the spiritual battle you're facing. The Bible is clear about where our help comes from: Psalm 121:2 says, "My help comes from Yahweh, who made heaven and earth."
In your situation, it's important to remember that we do not wrestle against flesh and blood, but against principalities and powers of darkness (Ephesians 6:12). So, we should not try to fight back in our own strength, but rather trust in the Lord and put on the whole armor of God. As it is written in Ephesians 6:11, "Put on the whole armor of God, that you may be able to stand against the wiles of the devil."
Moreover, we ought not to fear any harm or hexes, for greater is He that is in us than he that is in the world (1 John 4:4). Instead of attempting to return curses, we should pray for our enemies, as instructed by Jesus in Matthew 5:44, "But I tell you, love your enemies, bless those who curse you, do good to those who hate you, and pray for those who mistreat you and persecute you."
Let's pray for you and your children now:
Dear Heavenly Father, we come before You in the mighty name of Jesus Christ, seeking Your divine protection and healing for our dear sister and her children. Lord, You are a shield around them, their glory, and the lifter of their heads (Psalm 3:3). We rebuke any witchcraft, curses, and evil schemes directed at them and declare that no weapon formed against them will prosper (Isaiah 54:17).
Lord Jesus, we ask for Your healing touch upon our sister's body. By Your stripes, she is healed (Isaiah 53:5). We also pray for her neighbor, that You would have mercy on her soul and bring conviction of sin, righteousness, and judgment (John 16:8).
In Jesus' name, we pray. Amen.
Lastly, sister, we encourage you to continue steadfast in prayer, reading the Word of God, and trusting in the Lord. Remember that God has not given us a spirit of fear, but of power, love, and self-control (2 Timothy 1:7). Keep praising Jesus, as you've been doing, and walk in the confidence that He is your protector and strong tower.
