Query: Prayers That Avail Much

this particular book has been around for a very long time...and with good reason...it is one of the best books for prayer guidance that i've ever found...not only does it guide the reader through prayers...it gives the appropriate references to support how they are used...an excellent tool for when you just can't seem to find the right words...it has also been recommended by some of the most renowned Bible scholars...accolades to Germaine Copeland
