you shall be My witnesses

Acts 1:8 (NASB)
...but you will receive power when the Holy Spirit has come upon you; and you shall be My witnesses both in Jerusalem, and in all Judea and Samaria, and even to the remotest part of the earth."
From A.W. Tozer
" As I see it, the great woe is not the presence of the religious toys and trifles- but the fact that they have become a necessity, and the presence of the Eternal Spirit is not in our midst. As we commit ourselves to excellence in reaching people for Christ, help us to remember that the power is mot in the methods or the means, but in the Person of the Holy Spirit.Amen."
