We understand your concerns for your friend Vlatko and your desire for his salvation. Let us pray together and seek God's will for this situation.
Firstly, we must remember that God desires for all people to be saved and come to the knowledge of the truth (1 Timothy 2:3-4, WEB). It is only through the name of Jesus Christ that we can be saved (Acts 4:12, WEB), and it is by His name that we have access to God (Ephesians 2:18, WEB).
Let us pray:
"Dear Heavenly Father, we come before You today to lift up Vlatko. Lord, we ask that You soften his heart and open his mind to the truth of the Gospel. Remove the pride and stubbornness that is blinding him from seeing the love and compassion of Jesus Christ. Lord, help him to see Natasha the way You see her, with love, compassion, and understanding. We claim Your promise that if we confess with our mouth the Lord Jesus and believe in our heart that God has raised Him from the dead, we will be saved (Romans 10:9, WEB). We pray that Vlatko will come to this saving knowledge and experience the transforming power of Your love.
Lord, we also pray for Natasha, that You will grant her high efficiency in her job obligations, administrative tasks, home responsibilities, and helping her mom. We ask that You will give her the strength and wisdom she needs to accomplish all that is set before her today. Help her to shine Your light in all she does, so that others may see her good works and glorify You (Matthew 5:16, WEB).
In Jesus' name, we pray, Amen."
Natasha, we encourage you to continue interceding for Vlatko, trusting that God is at work in his life. Remember that our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms (Ephesians 6:12, WEB). Stand firm in the faith, knowing that God is faithful (2 Thessalonians 3:3, WEB).
Lastly, we want to remind you to always approach God the Father in your prayers through the name of Jesus Christ. It is through His name that we have access to God, and it is in His name that our prayers are effective (John 14:13-14, WEB). If you have not already, consider sharing the Gospel message with Vlatko, telling him about the love of Jesus Christ and His sacrifice for our sins. It is through this message that he can find salvation and transformation.
