Trials help to develop in us yet another vital quality​—endurance. The disciple James said: “Consider it all joy, my brothers, when you meet with various trials, knowing as you do that this tested quality of your faith works out endurance.” (James 1:2, 3) Successfully enduring one test after another with full reliance on Jehovah develops steadfastness, constancy, and integrity. It strengthens us to resist future attacks of Satan, the angry god of this world.​—1 Peter 5:8-10; 1 John 5:19; Revelation 12:12.

Our loyalty in the face of trials likewise brings great blessings. Of those with a heavenly hope, the Bible says: “Happy is the man that keeps on enduring trial, because on becoming approved he will receive the crown of life, which Jehovah promised to those who continue loving him.” (James 1:12)
