2 Petro 1 : 8 2nd Peter chapter 1 verse 8

Maana mambo hayo yakiwa kwenu na kujaa tele, yawafanya ninyi kuwa si wavivu wala si watu wasio na matunda, kwa kumjua Bwana wetu Yesu Kristo.
soma Mlango wa 1

For if these things are yours and abound, they make you to be not idle nor unfruitful to the knowledge of our Lord Jesus Christ.
