I don't use the name 'Jehovah' in prayer. There is no evidence that Jesus ever used the name 'Jehovah' ... rather that is Watchtower speculation and conjecture that he did. Jesus always paryed to his 'father' ... and even his so-called "model" prayer that the Watchtower loves to hammer, the famous Lord's Prayer, Jesus opened with "our Father" ... clearly teaching us to pray to the Father, and not some name pronounced Jehovah, or Yahweh, or anything else. Even Jesus dying words were to his Father ... the concept was to teach us that as Christians we are family.
The Watchtower religion has merely taken the name Jehovah and embellished it into a part of their marketing package ... to advance their religious cause, and corporate growth.
