Ooooh, awesome proverb. I'll have to try and use that one sometime.
Recently I tried planting a seed of doubt. Our toddler called my husband by his first name and my husband was upset. I asked him why, was it because using his name wasn't as personal as his speical role of "Daddy?" He said yes. Then I said that is how I feel about using God's name. Jesus and his disciples said "Father" or "God" which indicated a close relationship and respect. I was met with silence, but the wheels were turning.
Now I'm waiting to show him how the name Jehovah in the NT is based on Bible translations from the 1500-1900s instead if the original Hebrew manuscripts like we thought!
