I just wanted to ask, Are you sure that these people know the Lord? I remember once, while in Mexico in 1974, my husband and I heard about a Catholic priest who was great with teens. We went to see him and after a very short while we realized that he was a commie in disguise.
That experience made me suspicious of Church christians, my Family experience made me suspicious of everyone else.
Our son has had several problems with the teacher's at his school, but it's not a Christian school.
Last year he did attend a Christian private school here, but we discontinued it as it was taking us to the poor house. On top of that, (oddly) because we were paying - thus supporting them, they took it a bit too easy on him and let him get away with some really naughty behaviour. Not his present school. They nearly kicked him out the first month and it was just what he needed to wake up.
Sorry if this sounds a bit rambling. It's late and my eyes are bugging me again.
This kind of thing makes me so sad to hear, but it has inspired me to pray for you, Jane. God bless your heart. It's maybe your "cross", but I'm going to pray for the Lord to really use you and strengthen you. Let's pray together, shall we, that something happens to really encourage you. I feel that you need something like that.
Watch the movie "Ghandi". I'm watching it with my son. I had seen it years ago when it was first released in the cinemas, but I forgot how inspiring it was. It might encourage you to keep a going. Kissy and hugs.
