"For whom the Lord loveth he chasteneth...If ye endure chastening...afterward it yieldeth the peaceable fruit of righteousness unto them which are exercised thereby" (Heb.12:6-11), this shows that the trials which God gives us lead eventually to our spiritual growth.
"Maana yeye ambaye Bwana ampenda humrudi ….. kama mkistshimili kurudiwa …. Lakini baadaye huwaleta wao waliozoezwa nayo matunda ya haki yenye amani" (Ebra. 12: 6 -11).
