Munange, it was the God Almighty who first issued orders about Kakka business. Read here:-
Thou shalt have a place also without the camp, whither thou shalt go forth abroad: And thou shalt have a paddle upon thy weapon; and it shall be, when thou wilt ease thyself abroad, thou shalt dig therewith, and shalt turn back and cover that which cometh from thee: Deut 23:12,13.
I laughed when a certain pastor preached about this. First of all, the Elizabethan English was something else, and the actual thing he was saying...brought me to much laughter. Yet it was very meaningful.
It was a great message actually, coz he was relating to Jesus. And how he became (what cometh from thee-sin) and was covered in the ground for three days to rise up triumphantly having put away our (what cometh from thee) forever.
So talk about Kakka, Jesus became our kakka so we might become the righteousness of God in Christ.
Much love people. Great week.
