What I like about the high gears is that we run fast, but not grow weary.
There is no difference in believers; we are all complete in Him. Just some take the exact same equipment and rev high in low gears ... they are burning out and going nowhere.
I've been there.
Lets encourage each other to shift, when we hear someones gear-box whining in the low gears, because we aren't suited for chugging along at the red-line.
Kurt, question not your worthiness, rather question if you are forgiven, and if you have come to full repentance. ~ God [Letters from God and His Christ - Volume 1 - Those Whom the Lord Has Cleansed Are Now Clean Now, and Worthy of the Kingdom]
