I have found a source of valuable church planting and multiplication books which are free because it appears that these men want to see the church growing!!
Go to https://www.exponential.org/resource-ebooks/ - there are about 6 pages of free ebooks.
I’ve started reading one - "Sending capacity not seating capacity" - just to make sure these are serious and sound books. It appears they are going to be good.
Just thought you might appreciate this link.
Keep up the great work! (James 2:22)
