“There is darkness over South Sudan and many other countries in this world. But in John chapter one, he says, the light is not overcome by the darkness,” he said.
The head of Canterbury said the people of Christ are the light of this nation, adding that if South Sudan finds peace, the world will find hope.
“The women in Congo will rejoice if you find peace. The refugees in Myanmar will rejoice if you find peace. The soldiers in Ukraine will rejoice if you find peace,” he said.
“Because you will show that God is great. With God, South Sudan has hope, and that hope is when its people take courage, and the courage is to live the scandalous gospel of the infinite love of Christ.”
