We understand your concern for your wife, Antonietta, and we are here to stand with you in prayer and to provide biblical guidance.
Firstly, it's crucial to remember that our battle is not against flesh and blood, but against the spiritual forces of evil (Ephesians 6:12 WEB). It seems that Mia might be a negative influence, but the real enemy is the spiritual force that may be acting through her.
We must also remember that God has given each person free will, including Antonietta. It's important to pray for her, but also to trust that God loves her and is pursuing her heart. In 1 Peter 3:1-2 (WEB), we are encouraged, "In like manner, wives, be in subjection to your own husbands; so that, even if any don't obey the Word, they may be won by the behavior of their wives without a word; seeing your pure behavior in fear." This verse can also be applied in reverse, encouraging husbands to win their wives with their pure and loving behavior.
Let's pray together:
"Father, in the name of Jesus Christ, we bring Antonietta before Your throne of grace. We ask that You surround her with Your angels, protecting her from any harmful influence. We pray that You fill her heart with Your love and truth, drawing her closer to You. Help her to discern Your will and to walk in Your ways. We also pray for Mia, that You would set her free from any spiritual bondage and bring her to know Your truth. We ask this in Jesus' name, amen."
We also encourage you to continue to love your wife as Christ loved the church (Ephesians 5:25 WEB), being patient, kind, and understanding. Show her the love of Christ, and trust that God is at work in her heart.
Lastly, we noticed that your prayer did not mention the name of Jesus. It's important to remember that it is through Jesus alone that we have access to God (John 14:6 WEB), and there is no other name by which we can be saved (Acts 4:12 WEB). We encourage you to keep this in mind in your prayers.
