I think Scripture can answer your question with authority.
No doubts.
However, I think you have to settle on the biblical answer yourself.
The sovereignity of God is found throughout all of Scripture.
I am sure.
God could not be God if His will was not done.
No question.
The God in the Bible is not a weak and anemic God in which man’s fee will can overpower God’s sovereign will.
The whole of the Bible, Old and New Testaments, teaches that man has freewill. The whole of the Bible, if condensed, could be summarized into these two sentences: “do good, and eschew evil”. The following verses are just a tiny glimpse of that. I found these verses by just doing a Bible search for “do good”:
Psalms 34:
14 Depart from evil, and do good; seek peace, and pursue it.
Psalms 37:
27 Depart from evil, and do good; and dwell for evermore.
Isaiah 1:
17 Learn to do well; seek judgment, relieve the oppressed, judge the fatherless, plead for the widow.
Luke 6:
27 But I say unto you which hear, Love your enemies, do good to them which hate you,
Galatians 6:
10 As we have therefore opportunity, let us do good unto all men, especially unto them who are of the household of faith.
Hebrews 13:
16 But to do good and to communicate forget not: for with such sacrifices God is well pleased.
James 4:
17 Therefore to him that knoweth to do good, and doeth it not, to him it is sin.
1 Peter 3:
11 Let him eschew evil, and do good; let him seek peace, and ensue it.
If you wanted to do an intensive research, and extract all the verses in the Bible that in one form or another enjoins on mankind to do good, to repent, and to avoid evil, you would find that it covers about three quarters of the Bible, Old and New Testaments. If man did not have the freewill to obey God or disobey Him, that would make God a liar, a cheat, and deceiver; because He throughout His dealings with mankind has commanded them to do something which He knew they could not do, because He had already programmed them to do what He had wanted them to do. You Protestants want to make God liar, which is a terrible sin and a great wickedness. God will punish you for it if you don’t repent of that wickedness.
Maybe we should start a thread on the attributes of God according to Scripture revelation alone?
What for? What good is that going to do you? There is only one attribute of God which you apparently don’t know about, that you need to learn, and that is that God does not lie:
Numbers 23:
19 God is not a man, that he should lie; neither the son of man, that he should repent: hath he said, and shall he not do it? or hath he spoken, and shall he not make it good
1 Samuel 15:
29 And also the Strength of Israel will not lie nor repent: for he is not a man, that he should repent.
Malachi 3:
6 For I am the Lord, I change not; therefore ye sons of Jacob are not consumed.
Romans 11:
29 For the gifts and calling of God are without repentance.
Titus 1:
2 In hope of eternal life, which God, that cannot lie, promised before the world began;
James 1:
17 Every good gift and every perfect gift is from above, and cometh down from the Father of lights, with whom is no variableness, neither shadow of turning.
It means that He doesn’t deceive either. He doesn’t play tricks on people. His language is straight, and He stands by what he has said.
