Gustavo Petro, the leftist former mayor of Bogota and an ex-member of the M-19 guerrilla group, has been elected president of Colombia. According to the BBC, Mr. Petro ran a radical campaign and pledged to fight inequality through free university education, pension reforms, and high taxes on unproductive land. He also promised to enforce agreed upon peace deals with the FARC and to negotiate with still-active ELN rebels.

Mr. Petro has a lot to deliver on. Pray for him and for Colombia during this transition of leadership.
