The Power to testify

"When the Advocate comes whom I will send you from the Father, the Spirit of truth that proceeds from the Father, he will testify to me.
And you also testify, because you have been with me from the beginning."  (John 15: 26 - 27)

Lord, fill us with you Holy Spirit that we will bear witness to you in the Lord.  Empower us with your Spirit of truth that we shall spread the knowledge of your name among our brothers.  Without you, we can do nothing.
