In different part of the world, from time immemorial human being pray using differnet language and words to speak to God, or to say to pray to God. Apparently the approach, the way they speak and even the language vary tremendously. Sometime it varies so much that one accuse the other of blaspheming, crossing the limits etc. But they don't realize that God understand all, He loves diversity and thats why the nature is full of diversity.
Here is a nice story i found in the website, Warrior of the Light by Paulo Coelho.
The languages that God speaks
A Spanish missionary was visiting an island when he came across three Aztec priests.
“How do you pray?” asked the priest.
“We have only one prayer, “ answered one of the Aztecs. “We say: “God, You are three, we are three. Have mercy on us.”
“Beautiful prayer,” said the missionary. “But it is not exactly the prayer that God hears. I shall teach you a much better one.”
The priest taught them a Catholic prayer and went on his way to spread the Gospel among others. Years later, on the ship taking him back to Spain, he stopped at that island once more. From the deck he saw the three holy men on the beach – and waved farewell to them.
At that moment the three began to walk on the water towards him.
“Father! Father!” shouted one of them, approaching the ship. “Teach us again the prayer that God hears, because we can’t remember it!”
“It doesn’t matter,” said the missionary, seeing the miracle. And he asked God to forgive him for not understanding before that He spoke all languages.
In Islamic Tradition where Prophet Muhammad, blessed be his soul says: God doesn't look at your appearance but He looks at your heart. So your work and your reward will be according to your hearts sincerity.
