Welcome to Unto The Hills Ministries,The key verse that spoke to me when God led me to do this was Psalms 121:
Psalms 121:1-2 I will lift up mine eyes unto the hills, from whence cometh my help. (2) My help cometh from the LORD, which made heaven and earth.
So we offer lessons, devotions, books, Sunday School lessons, etc. for free because the Bible tells me
Mat 10:8 Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.
Check out the site for some free resources, check out The Blog for devotions, short Bible studies and the like, and be sure to drop me a line and let me know what you think (or a topic that I have not covered that you might want to know about).
Thanks and God bless you as you seek after Him.
