This is because God can compare us with Christ, a man like us who was tempted to sin - e.g. to be angry - but who overcame every temptation.
Hivi ni kwa sababu Mungu aweza kutulinganisha na Kristo mwanadamu aliyekuwa kama sisi alipojaribiwa kufanya dhambi - kama kukasirika - bali alishinda kila jaribu.
