Ex-Mukurweini MP Kabando wa Kabando has weighed in on Tuesday's prayers at the Nyayo stadium hosted by President William Ruto.
According to Kabando, the gathering was full of only allies of the president.
He went on to say that it was wasteful to hire and ferry crowds for worship services when the country is battling famine.
"Kenya is a secular state. Yes, the Constitution recognises sanctity and belief in Almighty God. But Kenya is not a theocracy. Today's Nyayo gathering was of UDA loyalties 'praise & worship'. Amidst famine, drought, and banditry: hired, uniformed, and ferried crowds. Sinful. Waste," Kabando said.
He added that it was also wrong to have certain denominations represented, and others left out.
Kabando said Kenyans must correct the government, whenever it is wrong.
"We sovereigns must call the bluff if/when the government strays. Arbitrarily convening so-called national prayers, that is, in fact, a partisan forum with some, not all, denominations is wrong. As in Nakuru, public institutions' buses are being misused to ferry UDA sycophants."
President had invited Kenyans to Nyayo stadium for National Prayer Day, on Tuesday.
Speaking during the interdenominational service in Nakuru, Ruto said the agenda will be to pray for rain and watch over the country.
"For those who will not be able to make it to Nyayo Stadium, have services anywhere and pray for the country," he said.
He also said his government has set aside seeds and fertilisers for agriculture, but all plans cannot go well if God doesn't provide rain.
"We need God in order to move forward," he said.
