Line in the sand

Joshua 24:15 “But if you refuse to serve the Lord, then choose today whom you will serve. Would you prefer the gods your ancestors served beyond the Euphrates? Or will it be the gods of the Amorites in whose land you now live? But as for me and my family, we will serve the Lord.”

A friend sent me this written by his son.
The Line in The Sand
 by David Sakowski, age 15

The swords have been drawn, There's a line in the sand, Now is the time to decide.
For which side do I stand? The devil with all his cunning, guile, and lies, Lurks to one side and awaits my choice. Do I go with the world and join his ranks?
But, alas, from the other side there came a voice! A voice of holiness, A voice of pure light, A voice that says "I will help you in your plight! I looked and saw, While the devil shouted, "No!" The splendor of a being, with a face that's aglow!
I cried, "Who am I to stand before you?" I fell to my knees and wept with remorse.
But the being said, "Rise, I mean you no harm, I sent my Son to die for the worst of the worst."
I stood up and looked into his eyes. I did not gaze in fear nor did I flee. He looked down with a smile on his face. I lifted my hands and said, "Please, help me." So he took me with his hand, His strong and mighty hand. And on that fateful day, I crossed the line in the sand.
