We all were taught manners . . .at least I hope so! Please and thank you being the basics, along with yes sir, no ma'am, etc. There is always a right and wrong way to speak, especially when speaking to those in authority! In fact, using manners often gains one favor, especially in today's world where manners and etiquette have often been forgotten and never taught! Asking the right way usually produces good results!
The Jews would not even speak the name of God. The Jews wanted to be certain not to misuse the Name of the Lord, so Adonai was used, in respect to His instruction in th Ten Commandments (Exodus 20:7). So when the Creator of the universe granted full access to His Throne, we too have guidelines! We must approach Him with respect, humbly, in awe, and yes, with a certain Godly fear! After all, He is not simply any king, any leader, but THE Lord of lords and King of kings!
So when we are in need, let's go to the proper authorities with respect. When we go to God, let's ask the right way!
