Anyone defending God is silly IMHO, but to your question of God's plan for you, it's a very broad answer. God's plan for you is very simple, go to heaven and worship him eternally. I mean point blank that's the prize at the end of the day. Consider ETERNITY in paradise vs 0-120 years on earth. What percent of infinity is 120 years?
The suffering and hardships we experience on earth are minutia in the grand scheme of things. I understand it's difficult to comprehend particularly when you don't believe in God but that's the answer IMHO.
You can choose to believe and have a relationship with God and go to heaven or choose not to and don't go to heaven everything else is just noise....
