A challenging question for you to think about, YHWH or God?
Person A knows His name as YHWH but chooses to use God because that is what is written in the Bible and what the church teaches. Person B knows His name as YHWH and chooses to continue to call Him YHWH and follows His commandments out of love.
Mishle/Proverbs 30:4-5 and Mattithyahu/Matthew 22:37 are mentioned to challenge your existing thoughts and beliefs.
May YHWH bless you and your house as you think about His Name.
