One of the hidden and embarrassingly false doctrines in Calvinism is double predestination, which is directly related to salvation and eternal life. It says:
By the decree of God, for the manifestation of His glory, some men and angels are predestinated unto everlasting life; and others foreordained to everlasting death. (Westminster Confession)
It is irrational for a Calvinist, who believes that, to evangelize. Why? Because (according to their theology) God has already decided in eternity past, apart from man’s free will and choice, to save some and let the majority go to eternal fire! They even have the audacity to teach that is for the manifestation of His glory! An evangelist is, therefore, wasting his time if murderous John Calvin was correct. Imagine that! To them, if a person is going to inherit eternal life, he will inherit eternal life apart from any Christian spreading the Biblical gospel (plan of salvation). Somehow, according to them, those chosen by God for eternal life will be regenerated, before they have faith, and enter paradise after death. As far as final salvation and actually entering God’s kingdom, Calvinism also has God creating some people, who are acting just as vile after regeneration as the hardened reprobate, to be irrevocably predestined to inherit eternal life regardless of their evil reprehensible behavior.
NOTE: Don’t allow a Calvinist, with their wordy semantic trickery, to deceive you through their never saved double talk about the elect living holy. Calvinists have a double message depending upon their audience! They don’t believe the elect have to live holy for eternal life! For example, they say when King David sinned with adultery and murder he remained saved all during that time!
Furthermore, under their poisonous view of the sin unto death and imputed righteousness, they also blatantly teach a license to sin. To make it even worse, they also teach the perseverance of the saints (or eternal security) is related to the gospel of grace! That makes their so-called gospel, another gospel, and places them under the dreaded anathema found in Gal. 1:8,9. The truth is, anyone (“whosoever”) can partake of eternal life (John 3:16; Mt. 11:28-30; 2 Pet. 3:9; etc.) and those who reap eternal life sow to please the Spirit not the flesh (Gal. 6:8,9). Don’t be deceived, God won’t be mocked through Calvinism or by anyone (Gal. 6:7-9). If you are listed in 1 Cor. 6:9,10; Eph. 5:5-7; Rev. 21:8; etc. you will not inherit God’s kingdom unless you repent, place your faith in the Lord Jesus and endure to the end (Heb. 3:14).
