Deut. 32:36 “For the LORD will judge His people (all the inhabitants of the earth). And He will have compassion on His servants (the church), when He sees that their (the church's) power is gone, And there is no one remaining, bond or free.
Heb. 10:29 How much more severely do you think someone deserves to be punished who has trampled the Son of God underfoot, who has treated as an unholy thing the blood of the covenant that sanctified them, and who has insulted the Spirit of grace? 30 For we know him who said, “It is mine to avenge; I will repay,”[a] and again, “The Lord will judge his people (all the people of the earth).”[b] 31 It is a dreadful thing to fall into the hands of the living God.
John 5:21–25. For as the Father raises the dead and gives them life, so also the Son gives life to whom he will.

You need to separate verses into "His people" meaning sometimes the elect, and "His people" sometimes meaning all people, so that you can sort them according to where they need to fit to keep your leaky boat afloat.

From the all-loving God's point of view, "My people" is all the people of the earth.
