What does it mean that God judicially gave them up?
God judicially gave them up means the sovereign God, acting as judge, handed rebellious unbelievers over to vile affections because of their behavior and rebellion. Since they chose to live at that level, He judicially let them sink one level lower. This was not loose language but a settled judicial action.
Les teaches that this is not loose language. A sovereign God judicially said that if they want to live at that level, then go down one level lower. The cause is their behavior, their unbelief, and their rebellion. He connects the same principle to Romans chapter 11 and Israel: Israel had every opportunity to know the will of God and had all things going for them, yet God dealt with their unbelief. In Romans 3:1-2, Paul writes after Israel has been blinded, asking what advantage the Jew had; the answer is much every way, chiefly because unto them were committed the oracles, or the Word, of God. God came down hard on Israel in their unbelief because they had the Word of God for centuries, ignored it, and refused to believe it. So judicial giving up is God's judgmental response to persistent rejection and rebellion, allowing them to go lower rather than forcing them higher.
For this cause God gave them up unto vile affections: for even their women did change the natural use into that which is against nature:
