However, they themselves refrain from using the Lord's proper name. They also feel uncomfortable when we use God - because they know we use it as his proper name. Someone on FR told me that they are ok with us using "Lord." So to be respectful of their religious beliefs, it would be probably wiser to use Lord than the hybridized "Jehovah" which is simply a fudging "trying to pronounce" the unpronounceable Tetragrammaton.
May the Lord bless you. LOL,LGE
