The Bible states God owns everything, including all people.
[Deu 10:14 KJV] 14 Behold, the heaven and the heaven of heavens [is] the LORD’S thy God, the earth [also], with all that therein [is]. [Psa 24:1 KJV] 1 [[A Psalm of David.]] The earth [is] the LORD’S, and the fulness thereof; the world, and they that dwell therein. [Psa 50:12 NIV] 12 If I were hungry I would not tell you, for the world is mine, and all that is in it. [Psa 89:11 KJV] 11 The heavens [are] thine, the earth also [is] thine: [as for] the world and the fulness thereof, thou hast founded them. [Job 41:11 NIV] 11 Who has a claim against me that I must pay? Everything under heaven belongs to me.“As the Creator of all things, God holds the certificate of ownership for all that is in the world, including the people in it.”

Even further, Christians have been bought/redeemed and we are now servants/slaves of Christ.
[1Co 6:19-20 KJV] 19 What? know ye not that your body is the temple of the Holy Ghost [which is] in you, which ye have of God, and ye are not your own? 20 For ye are bought with a price: therefore glorify God in your body, and in your spirit, which are God’s. [1Co 7:23 KJV] 23 Ye are bought with a price; be not ye the servants of men. [1Pe 1:18-19 KJV] 18 Forasmuch as ye know that ye were not redeemed with corruptible things, [as] silver and gold, from your vain conversation [received] by tradition from your fathers; 19 But with the precious blood of Christ, as of a lamb without blemish and without spot:“God doesn’t just own the universe. He owns you and me. We are twice his—first by creation, second by redemption.” Randy Alcorn

Paul reminded the Corinthians that ownership of their bodies had been transferred to Christ. They no longer had the right or freedom to use their bodies any way they wished. Just as slaves were purchased in the ancient world, we were bought with the price of Christ’s blood on the cross. We now belong to Him (1 Corinthians 7:22). We don’t have the right to rebel against our Master by using our bodies in ways He forbids.
