I have heard this several times that God's sovereignty and man's freedom are like two parallel lines that will meet in eternity. Thanks to Dr. R.C. Sproul, he has debunked this ideology.
In the above picture, you see two railroad tracks that run parallel to each other. If you look off into the distance, it does look like they meet on the horizon. However, in reality, they do not. If these two tracks meet, 1) they are not parallel to each other, and 2) the train and all the ppl on it are in grave trouble, as they will crash. So, in reality, God's sovereignty and man's "freedom" will never meet anywhere.
Man does have a "freedom", but this "freedom" is confined to his nature. Look no further than Joseph being betrayed and sold into slavery by his brothers. They wanted to kill him, but one of his brothers, I think it was Reuben, talked them out of doing that, and sold him into slavery instead. No one coerced them into doing this, as they freely and gladly ridded themselves of their younger brother. As Joseph told them later, "you did it for evil, God did it for good." So there's man's freedom and God's sovereignty in full view.
Then there's the cross of the Christ. As Peter stated
"this Man, delivered over by the predetermined plan and foreknowledge of God, you nailed to a cross by the hands of godless men and put Him to death."[Acts 2:23] Again, no one coerced them into having the Christ crucified. They acted in accordance with their wicked hearts, as they hated the Christ with nary a cause to do so. As the Christ plainly stated, ‘THEY HATED ME WITHOUT A CAUSE.’[John 15:25]
So, the sooner ppl realize that God's sovereignty and man's "freedom" will meet nowhere, and that both are biblically true, the sooner we can go on to debating real truths.
