pray that God will bring my Grandparents and aunt to salvation

Lord I pray you will touch and soften the heart of these grandparents and the aunt of this guest too. Open their spiritual eyes and ears so they will listen to your Holy Spirit talking to their heart. May they come to know you as their personal Savior before it's too late for them, and make you the cornerstone of their life. I thank you in advance in Jesus Precious Name, always giving you all the Honor and the Glory to whom all power belongs, Amen!
