Good point. They don't like that name one bit. There is power in that His name.
Acts 4:7-12 (New International Version)
7 They had Peter and John brought before them and began to question them: "By what power or what name did you do this?"
8 Then Peter, filled with the Holy Spirit, said to them: "Rulers and elders of the people! 9 If we are being called to account today for an act of kindness shown to a cripple and are asked how he was healed, 10 then know this, you and all the people of Israel: It is by the name of Jesus Christ of Nazareth, whom you crucified but whom God raised from the dead, that this man stands before you healed. 11 He is
" 'the stone you builders rejected,
which has become the capstone.' 12 Salvation is found in no one else, for there is no other name under heaven given to men by which we must be saved."
The WT are like the Sanhedrin
7 But to stop this thing from spreading any further among the people, we must warn these men to speak no longer to anyone in this name."
18 Then they called them in again and commanded them not to speak or teach at all in the name of Jesus.
Thus they talk all day long about "Jehovah" and his witnesses, not Christ's
Acts 1:8 (New International Version)
8 But you will receive power when the Holy Spirit comes on you; and you will be my witnesses in Jerusalem, and in all Judea and Samaria, and to the ends of the earth."
All the best, Stephen
