Craig is a man whose version of apologetics involve making everything as convoluted as can be. Simpler explanation: The universe is God’s. God has no sin in Him. God hates sin. All humans have sinned and are evil and are guilty. God could strike us all down instantaneously and send us to hell and would be just, good, and correct. We have no right to life, God creates us and gives us the chance and information needed to repent and turn to Him. In which case He lavishes us with undeserved mercy and grace. If we dont then we remain guilty and continue in our sins. Every breath we breathe is mercy from God. You are guilty and deserve death. Repent and pray for mercy.
In the Canaanite example, God can use any army He wants to strike down another nation, just as He used Babylon to strike down the sinful Israelites. What are some of the things that the Canaanites were doing that were evil thus making God want to crush them and drive them from the land? Read Leviticus 18: Parental incest, sodomy, abortion, beastiality, all manner of sexual sin and desecration of God’s creation and design. Its God’s universe with God’s rules, and if He says “dont have sex with animals” and then the Canaanites do so, He is in no way unjust for striking them down.
Similarly, the people of Sodom tried to butt-rape some angels in Genesis 18, so God rained down fire and destroyed them.
A worldview that doesn’t acknowledge your own sinfulness and the sinfulness of all humans will never understand God’s sovereignty. But when you understand that God extinguishing evil is in fact justice, you will understand the universe much better, and then when you realize that God’s mercy is above and beyond and comes purely from His love for us that exceeds sheer justice. This great Mercy and Love displayed in the flesh by God the Son Jesus Christ brutally dying on a cross to save YOUR soul, and creating possible reconciliation with God through His suffering, death, and His triumphant resurrection. He has paid it all so that you might be forgiven of your sins and made right with God, you didnt earn it and your own actions condemn you, but the penalty has already been paid for those who put their faith and life and loyalty in the glorious righteous Lord Jesus Christ.
Please pray on these matters and read the Gospel of Matthew. This is the truth of the universe, and it is not the will of the Father that any should perish
