Calvinists believe that not everyone has the right to freely get saved out of their own choice. They believe that the Lord has to elect or choose (they call that election) which person can go to heaven or to hell.
The easiest way to debunk that is to prove from the Bible, in numerous verses that God does not pick and choose who goes to heaven and who goes to hell. He said whosoever has a right. ‘whosoever’ means anybody has the right to believe on the Lord Jesus Christ for their salvation.
John 3:15-16 “That whosoever believeth in him should not perish, but have eternal life. For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life.”
John 11:26 “And whosoever liveth and believeth in me shall never die. Believest thou this?”
John 4:14 “But whosoever drinketh of the water that I shall give him shall never thirst; but the water that I shall give him shall be in him a well of water springing up into everlasting life.”
John 12:46 “I am come a light into the world, that whosoever believeth on me should not abide in darkness.”
Acts 2:21 “And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.”
Acts 10:43 “To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.”
Acts 13:26 “Men and brethren, children of the stock of Abraham, and whosoever among you feareth God, to you is the word of this salvation sent.”
Romans 9:33 “As it is written, Behold, I lay in Sion a stumblingstone and rock of offence: and whosoever believeth on him shall not be ashamed.”
Romans 10:11 “For the scripture saith, Whosoever believeth on him shall not be ashamed.”
In John 2:15-16, it says ‘whosoever believeth in him…’ not the elects. Calvinists claim that ‘whosoever’ cannot be referring to every single individual but rather to every single individual who believes and comes to Christ. Calvinists will say the verses say ‘whosoever believeth’ so that means it’s only talking about whosoever believes, thus it’s a specific category of people, it’s not everybody in the world.
To explain plainly (from Calvinist’s point of view), the people who believed in Jesus Christ for salvation are the saved people. Saved people are called the elect, that’s what the Bible says. So these verses are only to saved people, not everybody in the world, thus this proves the elect.
This argument of theirs, we can take it for granted that they gain eternal life by being in a group of people who believe. But that’s the point of the verse, if we believe in Jesus Christ then we join and get in that particular group. It’s not God picking and choosing, ‘You’re going to believe, you’re not going to believe’. No, God is simply saying anybody who chooses to believe in Jesus Christ, will have eternal life.
In these passages, we’re going to notice that when the Bible says whosoever, it’s simply pointing out the fact that the individual becomes part of the group when he does something. It’s not by God picking and choosing. Whosoever is referring to the particular group who is doing that particular action.
Genesis 4:15 “And the LORD said unto him, Therefore whosoever slayeth Cain, vengeance shall be taken on him sevenfold. And the LORD set a mark upon Cain, lest any finding him should kill him.”
Exodus 12:15 “Seven days shall ye eat unleavened bread; even the first day ye shall put away leaven out of your houses: for whosoever eateth leavened bread from the first day until the seventh day, that soul shall be cut off from Israel.”
Deuteronomy 18:19 “And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him.”
1 Chronicles 11:6 “And David said, Whosoever smiteth the Jebusites first shall be chief and captain. So Joab the son of Zeruiah went first up, and was chief.”
Ezra 6:11 “Also I have made a decree, that whosoever shall alter this word, let timber be pulled down from his house, and being set up, let him be hanged thereon; and let his house be made a dunghill for this.”
Proverbs 6:29 “So he that goeth in to his neighbour’s wife; whosoever toucheth her shall not be innocent.”
Proverbs 20:1 “Wine is a mocker, strong drink is raging: and whosoever is deceived thereby is not wise.”
James 2:10 “And saith unto him, Every man at the beginning doth set forth good wine; and when men have well drunk, then that which is worse: but thou hast kept the good wine until now.”
In Genesis 4:15, the ‘whosoever’ here, does God mean only a certain category that He elect? No, He’s saying here anybody. This anybody is referring to this group who does this particular action. It’s referring to anybody who does the action of slaying Cain.
It’s the same thing with John 3:15-16, it’s referring to anybody in this world who does a particular action of believing on Jesus Christ, they gain everlasting life.
