Spirit of Worship

According to Jainism, there was a frog in a pond in Rajgiri City. Once there came the Samosharan of Lord Mahaveera. All the citizens went to worship Lord Mahaveera. The frog also made up his mind to worship. The frog took a lotus petal in his mouth and set out towards Samosharan. King Srenik was also going towards the Samosharan riding on his elephant. When the frog was crossing the way, suddenly the elephant stamped the frog. It died at once. By the spirit of worship, the frog became a god in the heaven and immediately came down in the Samosharan and worshiped Lord Mahaveera. So when a frog can take birth in heaven by the spirit of worship, then why will human being not get happiness and peace by worshipping God?
