Suffering is the product of the universal sin of mankind. See Genesis 3:14-19.
Suffering may be the result of your life choices. See Galatians 6:7-8.
Suffering is not necessarily judgement for personal sin. Job 1:1; 2 Kings 13:14.
Suffering is not a permanent problem, it will end. See Revelation 21:3-4.
Suffering may be allowed to test your faith. See Job 1:8-12; 2:3; 1 Peter 1:6-7.
Suffering may be allowed to bring glory to God. See John 9:1-3. Your response to suffering to those that are watching may also serve as a testimony of God’s grace and help in your life which would cause others to trust in God.
Suffering can lead us to spiritual growth. See James 1:2-4; 2 Corinthians 1:8-9; Genesis 41:52. The only way we can grow and bear fruit through suffering is in properly responding to our suffering — not reacting to it. Responding requires intention. This means that you approach suffering from God’s perspective on it. Rather than reacting to our suffering through anger or losing heart, we fix our eyes on Jesus. See 2 Corinthians 4:16-18.
Suffering reminds us that we serve a God who suffered with us and for us. See Isaiah 53:3-5.
Suffering prepares and equips us to comfort others who are suffering. See 2 Corinthians 1:3-4.
Suffering does not mean God is withholding His love from us. See Romans 8:35-39.
Why does Jesus still bear the scars on his resurrected body? To remind us that God is not only aware of our suffering, He was willing to submit to it to allow us to overcome it.

God never wastes your suffering. He redeems it for a greater purpose.
