"Opposition Congress is spreading lies against this government and BJP workers need to counter them by explaining the real position to the people of the state," he told party workers in Gandhinagar.
A meeting of BJP workers was organised in Gandhinagar to form a strategy for the upcoming state assembly polls.
"For the last 10 years, the Opposition has been spreading lies against this government, but they have not succeeded," Modi said.
"The Congress is living on statements issued in media, but our real strength is faith that the people have put in us by voting us to power again and again," a statement quoted him as saying.
"This election has to be taken as a challenge by every party worker and team BJP will win it with flying colours. This party runs on the power of its workers," he claimed.
Other state BJP leaders like state unit president R C Faldu and national general secretary Purshottam Rupala also addressed the meet.
