Here’s one of the prayers…

Jesus, teacher and guide, we seek to know You as we grow in faith.
It is by our works that we show this faith.
Bless our school community with Your presence.
We ask that you continue to inspire us to further Your kingdom,
so that our faithfulness brings Your light to the world.
We make this prayer in Your name.
+Amen.
