"And it came to pass that while they were thus conversing one with another, they heard a voice as if it came out of heaven; and they cast their eyes round about, for they understood not the voice which they heard; and it was not a harsh voice, neither was it a loud voice; nevertheless, and notwithstanding it being a small voice it did pierce them that did hear to the center, insomuch that there was no part of their frame that it did not cause to quake; yea, it did pierce them to the very soul, and did cause their hearts to burn
And it came to pass that again they heard the voice, and they understood it not.
And again the third time they did hear the voice, and did open their ears to hear it; and their eyes were towards the sound thereof; and they did look steadfastly towards heaven, from whence the sound came.
And behold, the third time they did understand the voice which they heard; and it said unto them:
Behold my Beloved Son, in whom I am well pleased, in whom I have glorified my name--hear ye him."
I am so grateful that the Lord continues to speak to us, even if we don't understand, or don't really listen the first few times. I'd be in a lot of trouble if the Lord's law was one strike and you're out.
On the other hand, I'm glad that he doesn't always make things easy, either. Heavenly Father reminds me frequently that he values patience and persistence!
