READERS: ANYONE WHO WANTS YOUR PRAYERS OR SPIRITUAL WARFARE TO BE CRIPPLED OR USELESS WANTS GET YOU TO STOP USING OR SAYING THE NAME!
The name matters very much. It means so much that many have conspired to hide or conceal the name (by taking control over Sunday schools and educational literature, etc.) I'll solve part of a 'riddle' for you:
One reason behind Matthew 7:21-23 is that they are using titles "lord, lord" rather than using
the name. The name being given and refusal to apply it is regarded as a sin (see Parable of the Talents). AFAIK, the term "god" is not necessarily a name, it regarded to be a title or points to a role or office. Yehoshua has {Note that 'eyeh'/'yeh' is encoded at the front of the name and that he specifically said he comes in his Father's name...} Specificity serves to is to prevent confusion with Canaanite gods. Of course, those who want to lead the sheep to the dragon's mouth will wish to blur the distinctions. There are those who suggest "all roads lead to God". There is a guy who has a series of videos on the book of Revelations, he seems to have a lot of "I think" mixed in there but he has reached the conclusion that effectively are only two roads: one is to the Great Dragon and one is to the Tree of Life. The distinction is in the specificity. So perhaps it is true in the sense that: 99.9999% of the roads lead you to the left hand and a specific, narrow path leads you to the Tree of Life? And perhaps that is exactly the message the OT and the NT paints.
Consider the statement, "Everyone should wear allegiance to the president." --what exactly do you mean by 'the president'. If you are not specific you might wind up as a subject of the Philippines. The same ambiguity games are played in the United States with jurisdictional names. When you say 'state of Missouri', what exactly do you mean because specificity means a lot!
Elijah dealt with the ambiguity crowd too:
If it didn't matter, 1 Kings 18 would not have been written for our edification.
A hungry dragon wanting to be fed will tell you lies to get you down in its gullet. Have fun with ambiguity? "Baal" means 'lord' (it is a title, as explained in the KJV "the LORD" refers to a specific name it does not mean "god" or "him" or "the awesome one" or "lord". Elijah specifically addressed the 'titles only' ambiguity crowd. The reason they do not like names is because of the power in the name. Casting out evil spirits or praying or healing "in the name of the lord" does not comply with scriptural requirements. Of course, since they want you to fail they discourage you from using the name, and hope you will simply stop believing rather than getting wise to the deception.
