Let me start by briefly commenting on the question - “Where is God when I suffer unjustly?” Answer - “He’s in the same place He was when His Son, our Lord and Savior, Jesus Christ, was dying a horrific death on the Cross.” He was there, in the midst of the suffering, right beside Jesus, weeping along with Mary.
Understand, that He was weeping. Understand the pain that a parent feels when they witness the suffering of their child. God the Father was going through a hell all His own during those moments, and the years prior to those moments when Jesus was falsely accused and attacked and called a fool and a devil.
I don’t think it would be accurate to say that God was incapable of intervening. Of course He was. He is God after all! But there was a bigger picture to that suffering than just the moments of pain themselves. Had not Jesus Himself earlier said: “The Son of Man must suffer many things . . . . He must be killed and on the third day be raised to life?” (Lk 9:22)
