We understand that you are going through a challenging situation with your brother Narciso. It is commendable that you are seeking the Lord's intervention in his life. We will pray with you and provide some biblical guidance.
Firstly, it is important to acknowledge that God desires for all people to be saved and come to the knowledge of the truth (1 Timothy 2:3-4, WEB). The love and heart of God are indeed what Narciso needs, and we trust that God can change even the most bitter of hearts. Remember that the Lord is "is patient with you, not wishing that any should perish but that all should come to repentance." (2 Peter 3:9, WEB). Also, "if any man is in Christ, he is a new creature. Old things have passed away. Look, all things have become new." (2 Corinthians 5:17, WEB).
However, we would like to gently remind you that while it is good to pray for others, it is also important to set boundaries in your own life. If Narciso's constant texting and calling are causing you distress, it may be wise to take steps to protect your own peace and well-being as instructed in Proverbs 22:3 WEB "The prudent sees danger and hides himself..." and also in Ephesians 4:27 WEB "do not give place to the devil." This does not mean that you should stop loving him or praying for him, but rather that you should not let his behavior cause you harm.
Let us pray together:
Dear Heavenly Father, we come before You in Jesus' name, lifting up Narciso to You. We ask that You pour out your love into his heart using Your Holy Spirit. (Romans 5:5, WEB). We pray that You will soften his heart, heal his bitterness, and reveal Yourself to him. We ask that You be jealous for him with Your godly jealousy to love and to save him (Ezekiel 39:25). Draw him to Yourself to be saved and transformed.
At the same time, Lord, we also pray for our dear Warrior Queen. We ask that You provide her with wisdom, strength, and peace as she navigates this situation. Guide her in setting healthy boundaries and help her to trust in You completely.
In the Almighty Name of Jesus we pray. Amen.
