He went on the warn: "Government of the people and by the people sets a single standard for all who hold power: you must maintain your power through consent, not coercion."
The turnout was 54%, Mr Baroud said, the highest percentage among Lebanon's three million voters since the 1975-91 civil war.
The campaign was marred by mud-slinging and accusations that large numbers of expatriate Lebanese were flown home for free to cast votes.
But former US President Jimmy Carter, who led a team of international observers, said he was encouraged by the way the election had been conducted and the response of politicians from all sides.
"The most important thing is to commend the people of Lebanon and the election authorities for a successful demonstration of the right of the people to express their will. They did it legally and properly, and one of the tests of a successful election is a rapid acceptance of the results," Mr Carter said.
is a country of deeply-fragmented religious sects, and this election broadly pitted Shia Muslim supporters of Hezbollah against Sunni Muslims and Druze supporting the 14 March coalition.

Popular discontent after that attack had forced Syria to withdraw its troops amid accusations of its involvement in the killing. The government in Damascus has strongly denied the claims.
A post-2005 unity coalition collapsed in November 2006, with the resignation of all six of its pro-Syrian ministers, stripping it of representation by Lebanon's largest confessional group, the Shia Muslims.
The following year parliament became deadlocked over filling the vacant presidency - and a unity government was only re-formed after the country teetered on the brink of full-scale civil war in May 2008.
Analysts say another fragile unity government is likely from this result.
A major division looks set to remain over Hezbollah's powerful guerrilla army, which pro-Western elements accuse of disrupting Lebanese stability but which Hezbollah supporters say is vital to resist the threat from Israel.
Hezbollah will demand that it retain a veto-wielding share of cabinet seats which it secured in last year's unity talks.
