The following are reasons God gives us in answer to why mankind suffers:
Scripture tells gives us reasons for our suffering, trials, tragedies, etc. They are:
Philippians 1:29:
For it has been granted to you on behalf of Christ not only to believe in him, but also to suffer for him
(we are refined/made perfect by suffering)
II Timothy 3:12-13:
In fact, everyone who wants to live a godly life in Christ Jesus will be persecuted, 13 while evildoers and impostors will go from bad to worse, deceiving and being deceived.
James 5:13-15:
13 Is anyone among you in trouble? Let them pray. Is anyone happy? Let them sing songs of praise. 14 Is anyone among you sick? Let them call the elders of the church to pray over them and anoint them with oil in the name of the Lord. 15 And the prayer offered in faith will make the sick person well; the Lord will raise them up. If they have sinned, they will be forgiven.
Hebrews 12:5-7:
And have you completely forgotten this word of encouragement that addresses you as a father addresses his son? It says,
“My son, do not make light of the Lord’s discipline,
and do not lose heart when he rebukes you,
6 because the Lord disciplines the one he loves,
and he chastens everyone he accepts as his son.”
7 Endure hardship as discipline; God is treating you as his children. For what children are not disciplined by their father?
James 1:2-3:
Consider it pure joy, my brothers and sisters, whenever you face trials of many kinds, 3 because you know that the testing of your faith produces perseverance.
I Peter 1:6-7:
In all this you greatly rejoice, though now for a little while you may have had to suffer grief in all kinds of trials. 7 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.
Romans 5:3-4:
Not only so, but we also glory in our sufferings, because we know that suffering produces perseverance; 4 perseverance, character; and character, hope.
And as was said this is not our home. We look forward to our eternal home with Christ Who redeemed us. As also was already stated, we were lost to God through b/c of our sin which all people carry in their bodies and which we as Christians have an obligation to defeat, mostly by overcoming evil with good as Romans suggests. It is in heaven that the curse of sin is removed, not until then. More could be said, but I'll leave it here.
