Here's our Lord Jesus in John 3:16:
“For God so loved the world, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life” (NASB)
Here's Arthur W. Pink, strict Calvinist1 and famed Reformed Baptist author, in his rendition of John 3:16:
“For God so loved believers, that He gave His only begotten Son, that whoever believes in Him shall not perish, but have eternal life”2
Do you think Pink has a point in substituting "believers" for "world" in John 3:16?
1Note: some Calvinist scholars refer to Pink as more than a strict Calvinist; they refer to him as a Hyper-Calvinist (e.g. Dr. Curt Daniel)
2The term “believers” is substituted based on an inference from what Pink wrote pertaining to the term “world” in John 3:16. He explained: ‘“Kosmos” is used of believers only: John 1:29; 3:16, 17; 6:33; 12; 47; 1 Cor. 4:9; 2 Cor. 5:19. We leave our readers to turn to these passages, asking them to note, carefully, exactly what is said and predicated of “the world” in each place’ (Arthur Walkington Pink, The Arthur Pink Anthology, Chapter 44).
