Suffering. Let God use it for good.
God uses suffering to remind us that there is more to life than this life. Suffering reminds us that this life is temporary. God also uses suffering to motivate us to want more than this life has to offer: to long for Heaven.
Suffering gives us a unique opportunity to glorify God: our reason for existing. When we glorify God, we reveal his goodness and make it clearer. We glorify God by continuing to follow him through suffering
God will redeem suffering, but redemption has a cost; even after we are redeemed, scars remain. God uses suffering to draw us to himself. People go to God more when they are hurt than when they are happy. Redeemed suffering is more like a blessing than a curse.
