The concept of love (particularly how God loves) is a bit different on Calvinism. On Calvinism God loves the elect. Jesus died and rose again, for the few elect. This means that by definition, God as described by the consistent Calvinist is not omnibenevolent. Of course, a Calvinist could redefine the word “love” as it relates to God and claim that it is “loving” for God to allow those he loves to go to hell when they simply could not choose otherwise. In fact, this is the approach that many Calvinists take.
Speaking of the incarnation of Jesus, Martin Luther said that there were three miracles involved. “The first, that God became man; the second, that a virgin was a mother; and the third, that the heart of man should believe this.” Many hearts do not believe this. While we evangelical Christians are celebrating the entry of divinity into the world through the miracle of the virgin birth of Christ, the world is filled with those who object to this classic Christian doctrine.
Even the idea of believing refers to individuals since only individuals can exercise faith; I do not see anything in the passage that would indicate that this “all” is restricted to something like all people groups, including some who can be saved. I do not think the passage even hints that this “all” is different from “all” including each person previously spoken of as under sin; of which “there is no distinction.” This understanding corresponds precisely with its usage before and in the following verses.
“Success” is the crown worn by those who have attracted the largest following. Church members desire chaplains to attend them and comfort them. They shy away from men of God who would proclaim the ultimatums of Truth to them. The admiration of godless ambition has gifted to the modern church a plethora of undisciplined complacent pew warmers. I say this only to state what I think is desperately obvious: we need revival.
