Greatest sin

Once Jesus was walking along the streets of a city. It was a slum area. He saw a young man rolling in dirt, dead drunk. He went to him, sat by his side and woke him up. The young man opened his eyes and saw Jesus. Jesus asked him: "Son! Why are you wasting your precious youth in drinking?" The young man replied: "Master!, I was a leper. You cured me of my leprosy. What else can I do?" Jesus heaved a sigh and walked away.
In another street he saw a man madly pursuing a beautiful woman. Jesus caught hold of him and asked him: "Son! Why do you desecrate your body by indulging in such a sinful act?" The man replied: "Master! I was really blind. You gave me vision. What else can I do?"
Jesus trudged along another street. He saw an old man crying bitterly. Jesus approached him and gently touched him. The old man wiped his tears and looked at Jesus. Jesus questioned him: "Why are you weeping old man?" The old man said: "Master! I was nearly dead. You granted me life. What else can I do except weep in this old age?"
In times of difficulty and distress, we cry out for God's help. But when God, out of His boundless love and compassion, responds to our prayer, we ignore Him and fall back into our self-centered life. One must guard oneself against this greatest sin of ingratitude towards God.
