1 Yohana 3 : 10 1st John chapter 3 verse 10

Katika hili watoto wa Mungu ni dhahiri, na watoto wa Ibilisi nao. Mtu ye yote asiyetenda haki hatokani na Mungu, wala yeye asiyempenda ndugu yake.
soma Mlango wa 3

In this the children of God are revealed, and the children of the devil. Whoever doesn't do righteousness is not of God, neither is he who doesn't love his brother.
