dga said in post 9:
Most of the problems in this world, are man made.
Satan can also be the one who causes people to suffer (Luke 13:16). Jesus came to counteract Satan's work in the world (John 10:10). Jesus miraculously healed multitudes of people (Matthew 12:15b) oppressed by Satan (Acts 10:38). And Jesus still miraculously heals some people today, sometimes through Christians who have been given the Spiritual gift of miraculous healing (1 Corinthians 12:9).
Christians, with their hope of eternal life (Titus 1:2), can look far beyond any temporal suffering they may be undergoing (2 Corinthians 4:16-18, Revelation 2:10-11; 1 Peter 4:12-13). God can permit some Christians to suffer in order to help them remain humble before him and others (2 Corinthians 12:7). Also, suffering can strengthen Christians spiritually (Romans 5:3-5). It can help them to stop putting any hope in that which is merely mortal and temporal (2 Corinthians 4:16-18, John 12:25, Matthew 10:37-39). Also, when God allows Christians to suffer, he provides them with his comfort to help them through their suffering (2 Corinthians 1:3-7).
We mustn't ever say that it's evil for God to allow human suffering. For the only way to eradicate any possibility of human suffering would be to eradicate any possibility of humans committing sin (John 5:14). And the only way to eradicate any possibility of humans committing sin would be to eradicate their free will. It's better for humans to have free will and for there to be the possibility of suffering, than for them to be robots with no free will and for there to be no possibility of suffering. By becoming a human in Jesus Christ and suffering and dying for our sins, God has made a way for us to retain our free will and yet escape suffering in hell forever for our sins. For as the human/divine Son of God, Jesus' suffering satisfied God the Father's justice (Isaiah 53:11), which requires an infinite amount of human suffering for sin (Matthew 25:41,46).
Also, suffering is like gravity, in that while it can cause us problems, who would want to live without it? For example, someone could say that God was cruel to create gravity because it sometimes causes old people to fall down and break their hips. But who would want to get rid of gravity and float off into space? It's the same way with suffering. Someone could say that God was cruel to create the possibility of suffering. But if God made it impossible for us to suffer, what could happen to us? For example, imagine that you went on a camping trip, built a campfire, and laid down in your sleeping bag near the fire and fell asleep. While you were sleeping, you turned over at one point in such a way that your hand went into the fire. But because of your ability to suffer, you immediately woke up and pulled your hand out of the fire, keeping your hand from getting badly burned. But if you had had no ability to suffer, you would have stayed asleep with your hand in the fire, and woken up in the morning with no hand: it would have been burned clean off.
So suffering can be a good thing when it causes us to draw back from something that will harm us. God sometimes brings suffering to those he loves as a way of chastening them and getting them to repent from a sin (Revelation 3:19, Hebrews 12:5-11). For God knows how much harm their sin will cause them (Galatians 6:8, Hebrews 10:26-29), while on their own they could be oblivious to the danger (Proverbs 14:12).
