(Romans 9:21) “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?”
God, our Creator, has the right over His creation. He is the one who declares if we have an eternal responsibility before Him or not.
Therefore, God can fashion a vessel that He may use honourably, or a common vessel in which He has no use or pleasure.
He has no obligation to extend His grace to all humans, because all are sinners and have been deprived of every claim to His mercy.
God is therefore totally able to save one and not another, to use one vessel honourably and another one commonly.
He is sovereign and there is nothing unjust in His sovereignty.
We may then say that it is irrational and arrogant for men to question God’s choice of certain sinners for salvation because everything that God does, must be and is JUST.
God’s grace is His own. None of the sinners have deserved it. Those who are saved, must thank God ONLY; but those who perish, must only blame themselves.
However, God receives, and does not cast out, those that come to Christ. The Truth, as it is in Jesus, lowers man as nothing, as even less than nothing, and shows God as sovereign Lord of all. And we are to submit to Him, not to go against His will. But the fault is in the hardened sinner himself.
It is the Lord alone who made us to differ; we should adore Him for His pardoning mercy and new-creating grace, and give diligence to make our calling and election sure.
As He says also in Hosea, “I WILL CALL THOSE WHO WERE NOT MY PEOPLE, ‘MY PEOPLE,’ AND HER WHO WAS NOT BELOVED, ‘BELOVED.’ AND IT SHALL BE THAT IN THE PLACE WHERE IT WAS SAID TO THEM, ‘YOU ARE NOT MY PEOPLE,’ THERE THEY SHALL BE CALLED SONS OF THE LIVING GOD.” (Romans 9:25-26)
“Grace and peace be multiplied to you in the knowledge of God and of Jesus our Lord” (2 Peter 1:2)
