An old unbelieving blacksmith said that he could refute any argument that a Christian could make. There was an old deacon there; he was a Baptist and he heard of it. He told his wife and they got down on their knees and prayed until 3 o’clock in the morning. That morning the old deacon hitched up and drove over to see the man. He went into the blacksmith shop and the unbeliever was standing there. The deacon stood before him and said, “My wife and I prayed for you until 3 o’clock this morning.” Then his eyes filled with tears and he sobbed and turned away. He couldn’t think of one of the arguments he had prepared. He drove back home and when he got there he said to his wife, “I’ve made an old fool of myself. It was all for nothing. When I saw him, I just told him that we had been praying for him, then I broke down and couldn’t think of another thing and came home”.
In the meantime, the blacksmith went into his own house and said to his wife, “I heard a new argument this morning.”
She said, “What was that?”
“Why,” he said, “the old deacon drove in to see me this morning and told me that he and his wife had prayed for me until 3 o’clock in the morning. Then he sobbed and went away.” And the critic said, “I’d like to talk to him.” They drove over and he told the deacon why he had come, and it was not long before the deacon had him on his knees and he was saved.
The strongest evangelistic tool is a broken heart for the lost.
For, as I have often told you before and now tell you again even with tears, many live as enemies of the cross of Christ. Philippians 3:18 NIV
