I use to listen to voices in my head. Sometimes i would hear the words "You're my son". I concluded that i heard what i wanted to hear. Maybe im wrong. I couldnt listen to those voices however because i heard many strange things that seemed random.
Many years ago, there was a man deeply thirsty and in a very dry place. As he was on his journey, he suddenly came across an overgrown well, obviously not used in any recent time.
There was an old bucket on a rope so he dropped it down the well and soon hauled up his first bucketful of water.
When he looked at the water, he was devastated as it was so filthy it was undrinkable. He immediately tossed the bucket and its contents back down the well and hauled up another bucketful. It was just as polluted as before, and as before he tossed it back. This continued for the better part of the day until he was exhausted and almost dying of thirst.
Then he heard the sound of another traveller, and suddenly a wizened old man appeared. He took one look at the bedraggled heap of a man beside the well, and lowered the bucket down for water.
"You're wasting your time" the first man cried through cracked lips!
Ignoring him, the old man hauled the bucket up, took one look, and tossed it on the track before throwing the empty bucket back down. He didn't even bother looking as he quickly tossed the first dozen or so buckets aside, only then did he look at the water, and with a grunt of satisfaction tossed that aside and then hauled the next bucket up.
With that bucketful, he immediately took a long swig, and with a sigh of satisfaction held the bucket of crystal clear water to the puzzled first man.
The moral of the story is that, when we first start, the well of hearing God's voice is so full of our own garbage thoughts, that the water is virtually undrinkable. However, as we keep hauling those buckets up, that water will only become clearer and clearer till it too becomes like crystal.
If we do nothing, that same garbage will remain in the well for ever more, and the drought of hearing the Lord will remain.
The voice of the Lord will get clearer as we put our spiritual ears into practise. The same with visions etc.
So don't slack, get going and put your spiritual ears and eyes to use.
