I am not here to propagate that, nor am I here to debunk it. There are plenty of web sites on either side of this out there that are doing the job. I am also not here to "pimp" David Komolafe's new book "365 Days of FEAR NOT" which is available on 8/31/2012 from fine retailers such as www.christianbook.com (no charge!). I just saw the cover art and thought it would do nicely for this topic.
In my opinion, it doesn't matter how many there are. It is splitting hairs on something which, in the long run, is not important. What is important is that the God of all creation, the Maker of Heaven and Earth, the One, True God in Whom there is only Truth said it at least once! That settles it. What was, is and will be all wrapped into one verse, pick a Fear Not verse with a promise, it is TRUTH. It does not need to be repeated. One and DONE. That's it. Just believe and accept the promise.
Joshua 1:9 (KJV)
"Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed: for the Lord thy God is with thee whithersoever thou goest."Even God has to tell Joshua (again!) "Hey, I told you already, 'You got this. You are brave, strong. Nothing to fear or to be confused about, I got your back and will ALWAYS be there!'"
Shouldn't that one time (especially coming directly from God to Joshua) be enough? What about for us? We have the luxury of having the Entire Word of God available to us 24/7 in print, audio, digital...you name it. We have all the diverse and various instances of God's promises to Fear Not.
We should be extremely fearless. Are you?
Rejoice and be glad.
