A good way to reach people on Halloween is through gospel tracts. This way you can witness to people as they come to your door, even if it is through the pamphlet and a piece of candy. I use this day to witness for Jesus. Even though I do it on the streets, doing it at your door is also a great way to reach people. Even on this dark day, we can shine our lights for all to see. Below you will find free gospel tracts (+Free Shipping) that you can order for this. God bless you.
