This is a popular question among non-believers and a reason why many claim there is no God. Or, why they believe in another God or religion such as Buddhism which explains this away as "karma". But as a Christian, what do you think is the reason God allows suffering?
It might be helpful to parse out different uses or meanings of the term 'suffering'.
#1) Suffering due to your own foolish/evil decisions
#2) Suffering due to the foolishness/evil of others
#3) Suffering due to 'forces of nature'
#4) Emotional pain
#5) Physical pain
These are sometimes intertwined. For example, if you were born on a floodplain and your town is devastated by a flood. That may be
#3. If you decide to rebuild and stay on the floodplain, knowing it's just a matter of time,
#1 compounds a second occurrence of
#3.
As a divine community of love, Yahweh is inherently interpersonal. True interpersonal relationships require choice. Choice is not real if the effects of the choice are erased or annulled.
The vast majority of suffering in the world either comes from
#1 and
#2 (the results of real human choices) or is exacerbated by it. Read
Dead Aid by Dambisa Moyofor an example of direct and indirect human evil compounding the effects of natural suffering in regards to humanitarian aid in the past two or three decades.
The Bible also indicates in several places (including Genesis 3 and Romans 8:19) that the created order is in some way affected by human sin which means that at least some of
#3 is also a result of human choice. For God to annul the effects of our choice would be to reject free-will which also negates real love choices and hence, interpersonal relationships of agape.
The cross of Christ is how Yahweh addresses human evil and suffering. And the church, empowered by the Holy Spirit is participating in the expansion of God's good rule by loving self-sacrificially and combatting evil with good. (1 Corinthians 13).
For
#4, all emotional pain is ultimately connected to human sin, even over death of a loved one because through sin, death entered the human story.
For
#5, physical pain is a gift, not a curse. It tells you something is wrong with how your body is interacting with your environment. God did not curse humanity with pain, but evil people can and do use the good pain mechanisms in our bodies to inflict harm. (Aside: Eve's pain in child birth was
increased as a result of sin
. There was already some pain involved.)
Importantly, willingly absorbing suffering for the sake of Christ and his Kingdom of Agape love is an intrinsic part of what it means to be a disciple of Jesus. Just as he absorbed the just consequences of sin into himself on the cross, we now do similar through the power of Christ's Spirit. What is forgiveness but absorbing the consequences of sin into ourselves because Jesus has forgiven us? (Ephesians 4:32) When we are reviled, we do not revile in return, we absorb the suffering of scorn and shame (1 Peter 2:23). We are promised suffering and are told to rejoice in it (Romans 5:3).
It is true that Jesus is very familiar with suffering (Isaiah 53) and unlike us, none of it was deserved. Instead he took it on willingly (2 Corinthians 5:21) for our benefit. Now we do likewise (1 Peter 2:21). One day all will be put right and no more tears or sickness or pain (Revelation 21:4) and death will be finally conquered. Until then, those who are in Christ have a new relationship to suffering. It is something we can choose to engage with, our of love, just like our glorious Captain and King.
