Rather than make arguements based on fallacious strawmen I have decided to write down the two views, Arminianism and Calvinism and contrast them. Understand that I am a Calvinist (though for the first five years of my Christianity I was an Arminian), however, I have spent a number of years studying these views both in theology and church history. I have great condensed them down to one or two sentences that do not fully explore the nuances of either belief.
Point One:
Arminian: Arminians believe that humanity's fall into sin is not total. They believe that "the will" is free from any influence from sin and/or God.
Calvinism: Calvinists believe that humanity's fall into sin is total. They believe that man's will is in bondage to sin, and in such condition is unable to seek after God, unless God first intervenes.
Point Two:
A: The election of the saints is conditioned upon the response of the believer to the offer of salvation.
C: The election of the saints is based unconditionally on the choice of the Father.
Point Three:
A: The atoning work of Jesus on the cross is effective to save all humanity.
C: The atoning work of Jesus on the cross is powerful enough to save all humanity, but is only effective to save those who the Father elected.
Point Four:
A: The saving grace of God can be resisted by the individual.
C: The saving grace of God cannot be resisted.
Point Five:
A: In classic Arminianism, preserverance of the saints was something that was not clear. However, in modern Arminianism, it is viewed that the believer can lose his/her salvation.
C: The believer may from time to time fall into sin, but will never fall totally and permanently into sin. Those that do fully and finally fall into sin were never believers to begin with.
With the two contrasted, it is clear that the JWs are more Arminian, if not fully Arminian.
A couple of points: Chalam, I appreciate your citings of Scripture. However, nothing in John 3:16 negates any teaching found within the doctrines of grace(i.e., Calvinism). Calvinists beleive that the "whosoever" do not make this decision of their own volition, but only after the Holy Spirit has enabled them to do so. This is confirmed in John 1:10-18, as well as in Romans 3:9-18.
I will post more later.
