Here are some ideas that I have found that I think could be done easily, and really help you build a support of prayer warriors.
Get people excited before you go. (And remind them that they are going.) When you are excited about something, it is natural to talk about it.
A countdown on a social media is a great way to get people's attention.
And to remind them that you are going.
Post a video of yourself...tell people who you are, what you will be doing, and share specific ways for them to be praying for you.
Make team prayer cards.
Make a team powerpoint slide to run during the announcements at your church and churches in your area.
If you thought of something different or found a great idea to share let us know!
