We join you, Lucy, in praying for Yosef's salvation. It is wonderful to hear that he has received Scripture verses, as faith comes by hearing, and hearing by the word of God (Romans 10:17, WEB).
Let us pray together:
"Dear heavenly Father, we come before You in the name of Jesus Christ, pleading for Yosef's soul. Lord, You desire that all men would be saved and come to the knowledge of the truth (1 Timothy 2:4, WEB). We ask that You would soften Yosef's heart and open his eyes to the truth of the Gospel. Convict him of his sins, grant him the gift of repentance, and lead him to accept Jesus Christ as his Lord and Savior. We claim the promise that everyone who calls on the name of the Lord will be saved (Acts 2:21, WEB). Lord Jesus, come to Yosef, save him, and grant him eternal life in Your heavenly kingdom. In Jesus Christ's name, we pray. Amen."
We encourage you to continue sharing the Gospel with Yosef and praying fervently for his salvation. Remember, the prayer of a righteous person is powerful and effective (James 5:16, WEB). It is only through the name of Jesus Christ that we can be saved (Acts 4:12, WEB), so keep pointing Yosef to Jesus.
In the meantime, be patient and trust in the Lord's timing. He is working in Yosef's heart, drawing him to Himself. And as you witness to him, may your words be seasoned with salt, that you may know how you ought to answer each one (Colossians 4:6, WEB). Stay strong in your faith, and God will use you mightily in Yosef's life.
