[Romans 9:15-24 NASB] 15 For He says to Moses, "I WILL HAVE MERCY ON WHOM I HAVE MERCY, AND I WILL HAVE COMPASSION ON WHOM I HAVE COMPASSION." 16 So then it [does] not [depend] on the man who wills or the man who runs, but on God who has mercy. 17 For the Scripture says to Pharaoh, "FOR THIS VERY PURPOSE I RAISED YOU UP, TO DEMONSTRATE MY POWER IN YOU, AND THAT MY NAME MIGHT BE PROCLAIMED THROUGHOUT THE WHOLE EARTH." 18 So then He has mercy on whom He desires, and He hardens whom He desires.
19 You will say to me then, "Why does He still find fault? For who resists His will?" 20 On the contrary, who are you, O man, who answers back to God? The thing molded will not say to the molder, "Why did you make me like this," will it? 21 Or does not the potter have a right over the clay, to make from the same lump one vessel for honorable use and another for common use? 22 What if God, although willing to demonstrate His wrath and to make His power known, endured with much patience vessels of wrath prepared for destruction? 23 And [He did so] to make known the riches of His glory upon vessels of mercy, which He prepared beforehand for glory, 24 [even] us, whom He also called, not from among Jews only, but also from among Gentiles.
In light of scriptures like the above, I just want a verse that actually SAYS that God commands every person without exception to be saved, before I blindly accept a claim on a website that God has made such a command as a FACT.
