True. God is soverign. But Jesus described Satan as “the god of this world”, and until this return this world remains a very dark place. God never intended that Adam and Eve would win either, but they did. He never intended that people sacrifice their children through abortion, but they do so every single day.
"Men's hearts failing them for fear, and for looking after those things which are coming on the earth, for the powers of heaven shall be shaken." (Luke 21:6)
