God often sends or allows affliction to strengthen our faith

"In this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. These have come so that your faith—of greater worth than gold, which perishes even though refined by fire—may be proved genuine and may result in praise, glory and honor when Jesus Christ is revealed" (1 Peter 1:6-7).

"As he went along, he saw a man blind from birth. His disciples asked him, "Rabbi, who sinned, this man or his parents, that he was born blind?"  "Neither this man nor his parents sinned," said Jesus, "but this happened so that the work of God might be displayed in his life" (John 9:1-3).

God disciplines those He loves

"My son, do not make light of the Lord’s discipline, and do not lose heart when he rebukes you, because the Lord disciplines those he loves, and he punishes everyone he accepts as a son" (Hebrews 12:5-6).

God will never gives us more than we can bear

"No temptation has seized you except what is common to man. And God is faithful; he will not let you be tempted beyond what you can bear. But when you are tempted, he will also provide a way out so that you can stand up under it" (1 Corinthians 10:13).

Affliction should draw us closer to God's Word

"It was good for me to be afflicted so that I might learn your decrees. The law from your mouth is more precious to me than thousands of pieces of silver and gold" (Psalm 119:71-72).

"Before I was afflicted I went astray, but now I obey your word. You are good, and what you do is good; teach me your decrees" (Psalm 119:67-68).

We should praise God while undergoing affliction

"Shout for joy, O heavens; rejoice, O earth; burst into song, O mountains! For the LORD comforts his people and will have compassion on his afflicted ones" (Isaiah 49:13).

"At this, Job got up and tore his robe and shaved his head. Then he fell to the ground in worship and said: "Naked I came from my mother’s womb, and naked I will depart. The LORD gave and the LORD has taken away; may the name of the LORD be praised" (Job 1:20-21).

Our future glory is worth enduring hardships

"I consider that our present sufferings are not worth comparing with the glory that will be revealed in us" (Romans 8:18).

God blesses those who persevere under trials

"Blessed is the man who perseveres under trial, because when he has stood the test, he will receive the crown of life that God has promised to those who love him" (James 1:12).

God can deliver us from affliction

"He has delivered us from such a deadly peril, and he will deliver us. On him we have set our hope that he will continue to deliver us, as you help us by your prayers. Then many will give thanks on our behalf for the gracious favor granted us in answer to the prayers of many" (2 Corinthians 1:10:11).
