Many great philosophers have thought and written about dualism, where life is composed of opposities and some have sought to see beyond this and see them as part of a larger system. This is called non-duality. One of the oldest duality is of free will and fate or human will and God's will. Many have sought to prove one and disprove the other, as the answer becomes easier to accept and easier to fit within the way we think.
The hard part about accepting this is that although time and reality as we know it is nothing compared to eternity, the illusion is thoroughly convincing. When you are lost in doing something you love, time goes by faster and when you are in great pain, time goes by much more slowly. Even though the spiritual world is more real, we can only understand it through faith and many doubt its existence entirely. But sometimes we get brief glimpses of this reality in situations that we cannot explain without a spiritual origin or causality.
Even though we have eternity, in only a few years away, we cannot wait while always keeping the faith in sight. We get distracted and lose our way. We spend our time on unimportant things and fighting about things that don't really matter. We have so little faith. Why is it so easy to believe the reality of what we know will perish quickly and struggle to accept the more pleasant and rational ultimate reality?
We see that the world does not make sense after spending years trying to control it. We become the play things of the natural world and we get pulled into its way of thinking. We get discouraged because we are impatient and are mentally and spiritually weak. Just as the disciples could not stay awake even a few hours, to pray in the garden of Gethsemane, before Jesus was placed on the cross, we give up far too easily.
Do not accept the reality that you see before you. Do not give up on God, because He will never give up on you. We see evil and pain in the world, like a snowball going downhill and speeding up and growing, as it travels. There is so little we can do naturally, but so much God can and will do. God decided long ago that people would control their own destiny. For those who love God, we wonder why he ever gave us free will, but those who hate him revel in this freedom and chain themselves to suffering, while thinking they are becoming more in control.
So yes we have complete freedom, to make the choices we do, but God can and will intervene to fix our mistakes as He wills. We each play our part like actors in the play, but God is the author of the play. We think we play by our own rules and think that God has abandoned us, until we grow older and realize that our quest for control is the road to our suffering. We need not give up on joy in life and accept pain as inevitable, but we do need to learn to choose God, regardless of the difficulty to master our own selfishness and how little we understand how this works. Faith is by definition blind.
The way free will and God's will (or fate) is meant to work is for us to choose God's will. We are given many choices in life, that matter little, but some choices define us. Instead of letting your circumstances define you, choose to have God transform you and your circumstances, not as a weak and passive observer, but as a willing and active partner. Don't choose God because He is all powerful; choose God because He is good and merciful.
Unfortunately, in life we have no guarantees, until after it ends. We need to make good choices and be responsible adults. It would be very immature of us to just expect God to solve all our problems, without putting any effort in to solve them ourselves. God wants us to be equal partners, in our choices in life, but He also wants us to grow up and be able to handle some things on our own. But is is ridiculously hard to have patience, when you know the pain will not end for many years. But, God understands, as He lived a very difficult life on earth as a person and He does and will intervene.
We just have to understand that God is not responsible for our suffering and so is not going to always bail us out. Just like when an adult breaks something, they must pay for its replacement or to fix it, so we, as the collective creators of pain and evil, must take responsibility and do our best to minimize this suffering, in ours and others' lives.
