Z_ I am praying for you and for O and T to walk with You and for them to find Christ's love and peace. The best and only thing Z_ can really do is to give this request to You and leave it at your feet for your saving grace. Perhaps if he invited them to go to church with Z_ and then a light-hearted lunch or brunch afterward. They can talk about the lady with the big hat, or what song they remember, just make it non-judgemental and easy. Talk about a sport team, do your remember that was your third grade teacher, whatever. You be the still small voice in their ears guiding and telling them what to do next. They will eventually hear the Holy Spirit, he won't be ignored. Keep praying, love God's to hear gratitude and he loves you.
