The doctrines of Calvinism begin with a philosophical position, and force the scriptures to fit. The reverse is what should take place. It is highly dangerous to base any doctrine upon selected texts rather than inductive Bible study.
Calvinistic philosophy ignores the teaching of "whosoever will" — rejecting it as a work that negates all God has done. This thinking results from confusing the means (personal faith in Christ) with the grounds (the gracious work of Christ) of salvation.
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.
And he is the propitiation for our sins: and not for our's only, but also for the sins of the whole world.
For whosoever shall call upon the name of the Lord shall be saved.
Whosoever believeth that Jesus is the Christ is born of God: and every one that loveth him that begat loveth him also that is begotten of him.
Whosoever shall confess that Jesus is the Son of God, God dwelleth in him, and he in God.
To him give all the prophets witness, that through his name whosoever believeth in him shall receive remission of sins.
And it shall come to pass, that whosoever shall call on the name of the Lord shall be saved.
Men and brethren, children of the stock of Abraham, and whosoever among you feareth God, to you is the word of this salvation sent.
Whosoever therefore resisteth the power, resisteth the ordinance of God: and they that resist shall receive to themselves damnation.
And I, if I be lifted up from the earth, will draw all men unto me.
And the Spirit and the bride say, Come. And let him that heareth say, Come. And let him that is athirst come. And whosoever will, let him take the water of life freely.
