Here we have yet another teaching of the "reformed", that is not what the Bible actually says. If, as it is claimed, that God gives saving faith only to the elect, then passages like 2 Thessalonians 1:8-9, make God to be unjust. Here Paul clearly says:
"In flaming fire taking vengeance on them that know not God, and that obey not the gospel of our Lord Jesus Christ: Who shall be punished with everlasting destruction from the presence of the Lord, and from the glory of his power"
God will punish those who do not "know Him", and "disobey the Gospel" of salvation.
How can God be just in doing so, when it is He who, according to reformed teaching, withholds saving faith from them in the first place, so that they cannot know or obey Him?
In Hebrews chapters 3 and 4, we are told that the children of Israel could not enter God's Rest, because of their disobedience, and lack of faith. Again, if it is God who did not give them this gift of faith/obedience, how can God punish them for their lack of faith faith/obedience, since He did not give them it in the first place?
In passages like Joshua 24:15, people are told to "choose" (have faith), between God and the devil. How can they be expected to "choose" God, unless they are able to?
This is a false teaching.
