Luckily, I found it online for you to read too.
"An old drunk once stumbled along a sidewalk heading for his home. His faithful dog saw him approaching and watched his every move. As he entered his home, his dog joyfully followed him. When the drunken man collapsed on the floor in his living room, the dog snuggled up to him, waiting for his master to wake up.
Suddenly, in the middle of the night, the old drunk was roused by the dog’s barking. The last thing he wanted was a barking dog! He staggered to his feet, grabbed a chair and threw it at the dog, then collapsed again.
It the morning he awoke to a shocking sight. Thieves had broken into the house in the night and stolen everything he owned —everything, that is, except a broken chair and a dead dog. His faithful friend had been trying to warn him of danger and he had killed the best friend he had."
The Bible teaches that you and I are created in the image of God. Thus, we have a moral compass called a conscience that acts as an aid for our lives. The Bible goes on to teach us that we can actually "seer" our conscience, that is to make it callus. A kid in my church started playing guitar recently, and he showed me some chords one day after youth group. After about 10 minutes of playing, the tips of my fingers ached severely. He laughed at me and then asked me to look at the tips of his fingers. They were covered in thick calluses. The calluses were formed from him practicing guitar, and in doing so, it took his tender fingers and turned them into rawhide.
This is what happened to the drunk man in the story. Over time, he became so comfortable with his conscience that he ignored it and even despised it.
And in the end he paid dearly.
God gave you a best friend.
It’s your conscience.
