The Lord is always upfront and honest with His children.
He doesn't tell us we may have trials - He says you will have trials. Trials that hurt both physically and mentally but are(somehow) for our good and His glory. Most of the time we haven't a clue what the Lord is doing with us. We'd rather not go through pain and trials; they hurt. A lot. They disrupt and can permanently change our lives. With changes we'd rather not make, thank you.
He calls us to trust Him. Complete trust. I remind myself He is God, the Creator of the Universe and I'm a formed pile of dust. But a pile of dust He loved/loves so much He sacrificed His Son for me. And so I trust Him from within the trials He sends. And wait for His revealing the reason to me, whether on earth or in heaven.

fire howls red fury
charred ash, remains shift.
flames skip-dance across
years, burning destruction,
hollow memories, pain.

I have tested you in the furnace of affliction."
