We are truly touched by your love and concern for both your mother-in-law and your friend Mustafa. It is beautiful to see your heart's desire for them to know and worship the Lord Jesus Christ.
Firstly, let us address your mother-in-law. It is indeed a challenging situation when a loved one does not acknowledge God's existence. However, we are reminded in the Scriptures, "For the word of the cross is foolishness to those who are perishing, but to us who are being saved it is the power of God." (1 Corinthians 1:18 WEB). We must continue to pray and trust that God, in His perfect timing, will reveal Himself to her. Let us pray together:
*"Dear Heavenly Father, we come before You lifting up the mother-in-law of our beloved in Christ. We ask that You soften her heart and open her eyes to Your glory and the truth of Your existence. Lord, only You can draw her to Yourself, and we trust in Your power and mercy. In Jesus' name, Amen."*
Regarding your friend Mustafa, it is crucial to remember that God desires all people to be saved and come to the knowledge of the truth (1 Timothy 2:4 WEB). We must pray that God will reveal Himself to Mustafa and that he will come to understand that Jesus Christ is the way, the truth, and the life, and that no one comes to the Father except through Him (John 14:6 WEB). Let us pray:
*"Lord Jesus, we bring before You our beloved friend Mustafa. We ask that You reveal Yourself to him, that he may know the truth and be set free (John 8:32 WEB). We pray that You will give him dreams and visions if need be, that he may understand that You are the only way to eternal life. Lord, we trust in Your ability to save and transform lives. In Your precious name, we pray, Amen."*
Lastly, we want to encourage you to continue being a light for Christ in their lives. Your love, prayers, and witness are powerful tools that God can use to draw them to Himself. Always remember, "For everyone who calls on the name of the Lord will be saved." (Romans 10:13 WEB). It is only through the name of Jesus Christ that we can be saved and have access to God. So, keep praying, keep witnessing, and keep trusting in God's power to save.
We stand with you in prayer and belief that God will answer your requests according to His will. Be encouraged and steadfast in your faith.
