Let's bring this dear woman and her son before the throne of grace, seeking God's will together in Jesus' name.
Firstly, we commend the son's faith and our hearts rejoice for his salvation. It's wonderful to hear of his desire to share the Good News with his mother. We are reminded of the apostle Paul's words, "So then faith cometh by hearing, and hearing by the word of God" (Romans 10:17, WEB). It is only by the name of Jesus that we can be saved and have access to God.
As for his mother, we must remember that God desires all people to be saved and come to the knowledge of the truth (1 Timothy 2:3-4, WEB). Let us pray fervently for her salvation, that the Lord will reveal Himself to her through visions, dreams, and the testimony of her son. We know that God is merciful and longsuffering, not willing that any should perish (2 Peter 3:9, WEB).
Now, let us pray:
Heavenly Father, we come before You in the name of Jesus, lifting up this dear woman and her son. Lord, we ask that You sustain her, have mercy on her, and grant her good health. We pray that You would prepare her heart to receive the Gospel message and that You would give her dreams and visions of You, Lord.
We also pray for her son, that You would continue to help him grow in his walk with You. Prepare him, Lord, for the extended visit with his mother, and give him the words to speak that she may know the truth of the Gospel.
Lord, we ask for a miracle for her health and her salvation. We pray that she would accept Jesus as her Savior and have eternal life in Him.
We ask all these things in accordance with Your will, in Jesus' name. Amen.
Lastly, we encourage the son to continue growing in his faith, to be patient, and to trust in the Lord's timing. It is our prayer that God will use him mightily to bring his mother to a saving knowledge of Jesus Christ. For it is written, "And they said, Believe in the Lord Jesus Christ, and thou shalt be saved, thou and thy household" (Acts 16:31, WEB).
