This is a GOD'S Honest Truth story - I swear upon the name of Jehovah.
You know, there's this guy I know, who used to take part in a different bible study group I belonged to. For whatever reason, that group broke up because of schedule conflicts and people moving away, etc. He used to be a greeter at Walmart and when I saw him a few years later at Walmart, he said to me "Hey, Mark!" (except that my name is not Mark). I didn't hear him and didn't realize that he called me by that name. The next time I saw him, he called me Mark again and I was too embarrassed to correct him. To be 100% honest I was truly honored that he recognized me at all. That was about ten years ago and to this day he still thinks my name is Mark. EVERY time he sees me, he doesn't just smile or say a bland hello. He calls me Mark.
I am not God or anything close to it. But I have to tell you the fact that this guy says anything at all to me - demonstrating that he recognizes me and is forward enough to greet me rather than just let me walk by unrecognized = a tremendous courtesy to me in my own mind. He knew my correct name when we were meeting regularly, but somewhere along the line confused it. I could get upset that he didn't think enough of me to remember and call me by my correct name. But am I really that spiteful? I am far from the holiest person on earth, but if we hypothetically take the holiest man on earth who does everything right but he only refers to God as the Dear Captain of My Salvation (truly meant to be a term of honor and not made in jest), is that holiest man alive really damned for eternity simply because he used the wrong name??? I cannot buy into that. I'm sorry.
MY God does not care if I call him Mark instead or Joe or Mike or Willie. My God knows that I love Him, that I praise Him, that I worship Him and He loves the fact that I pray to Him and ask him to bless me and my family and friends.
In the wise words of Thomas Merton:
My Lord God, I have no idea where I am going. I do not see the road ahead of me. I cannot know for certain where it will end. Nor do I really know, and the fact that I think I am following Your will does not mean that I am actually doing so. But I believe that the desire to please You does in fact please You.
I have zero fear that God will ever strike me down or damn me to hell for not calling him Jehovah. If I desire to please Him, that desire IN AND OF ITSELF pleases Him. Not some crazy technicality that I called Him by the wrong name.
