Sinners are saved only if they have been chosen for redemption in Christ Jesus. Ephesians 1:3-4
It is the election, love, and grace of God for individuals that saves. Romans 9:13
Without these qualifications, no man will call upon or believe in the name of God.
"Reprobate" is a state of being in disfavor with God.
The King has the authority and right to name who He favors and those He will invite into His court.
Reprobates hate to hear this truth . . .
The biggest sin of Calvinism and the one that will cause you to be lost is that you believe that God is unjust. If God only chose some to be saved and damned the rest to hell, you have an unjust God.
Calvinism is self defeating. We are saved and justified by faith in God and his Son Jesus Christ.
If you believe in predestination, then you must also believe that God is unjust. Worse yet, Calvinist do not believe that Jesus atoned for the sins of the whole world.
You do not have saving faith in God, nor do you have saving faith in his Son Jesus Christ.
