Lots of people would do well to listen to you. You have a lot of knowledge in the scriptures.
I would also like to add......His Grace, mercy and perfect justice would not be known to his creatures if He did not allow us to sin by our own volition.
Our freewill choice to believe upon His Son, reveals His love,grace,mercy and perfect justice. All attributes of God that we would not know without a freewill to sin and a freewill to be saved from the consequence of that sin.
The only person that was determined in advance to die from sin is the Lord Jesus Christ. All men have the opportunity, from their personal volition to be declared justified through His Son......no man is left out of making that choice. Other wise His prefect justice would be less than perfect and He would not be a righteous judge.
If even ONE man was denied the opportunity to believe on His Son, He would be UNJUST.
New American Standard Bible
Say among the nations, "The LORD reigns; Indeed, the world is firmly established, it will not be moved; He will judge the peoples with equity."
If he saved ONE person through His Sovereignty or denied ONE person of their choice to believe through His sovereignty, His perfect justice as the Judge would be compromised.
He can't use one divine attribute(sovereignty) to compromise another divine attribute(perfect Justice or righteousness.)
