Setting up an environment where students will be open to receiving the Gospel Message is key to each time you gather with them. Seek to create and foster conditions that will assist your students to be open, docile and more ready to receive the message that you will be proclaiming during a given lesson.
3 Ways to do this:
1) Set up a sacred space
2) Re-arrange the desks and chairs in your meeting space in such a way that it feels less like a typical classroom and more like a place where they can be aware that you have been expecting them and that God is going to be a part of what they are going to learn today.
3) Witness to students your joy and enthusiasm of being with them from the moment they walk into your meeting space to the time they leave.
