“Christ suffered for our sins once for all time. He never sinned, but he died for sinners to bring you safely home to God. He suffered physical death, but he was raised to life in the Spirit” (1 Peter 3:18, NLT).
The biggest unanswered questions in life revolve around suffering: why do bad things happen to good people? Why is life so full of misery? Why doesn’t God do something? Where is he when we need him? If he’s so powerful and all-knowing, why doesn’t he prevent the tragedies that daily plague us? Some try to make sense of it all by going so far as to say God is either teaching us lessons or punishing us, but these statements aren’t real answers and offer no comfort.
I don’t have answers either, but what I do know is Jesus understands. He came as a human to enter into our suffering. He experienced all the bad things we have to endure, but no doubt on a deeper level. Because he was both human and God at the same time he suffered with us and for us for all time, from the beginning of human history all the way to whenever it ends. Our suffering is his—he owned it and owns it still.
God didn’t promise us a fairy land where bad things never happen and nothing hurts, but he did promise and deliver the Comforter, the Holy Spirit, who helps us through the pain and reminds us this life isn’t all there is. One day our suffering will end and he will give us the answers, but for now he has left us with his peace, which we can have even through our pain and struggles.
Jesus - Son, Savior, God 
The reason why we ask “why” is because we can’t comprehend “why” He allows suffering.
But we cannot say He isn’t interested or doesn’t care because He got involved (as you point out).
We just have to trust Him and simply understand that just because we can’t think of a reason “why” doesn’t mean there isn’t a perfect reason “why” He does.
Keep up the good work,
Mike
