Hold on I know God rains on the just and the Unjust alike. Also Times and seasons God ordain. That is not the grace by which we are saved through faith. Is 55:11 and Rom 2:16 do not over ride The words of Jesus who is the Supreme authority when HE is speaking even greater than John Calvin TULIP.
"a failure of God's word to effect salvation means that God's purpose in sending forth His word isn't always to save."
The issue with this statement is it doesn't take into consideration Jesus is the WORD. He came to save that which is lost. He said in John 3:16 the love of God for the world he gave his only son so that none should parish.
He also said why men don't get saved.
18“He who believes in Him is not condemned; but he who does not believe is condemned already, because he has not believed in the name of the only begotten Son of God.
19And this is the condemnation, that the light has come into the world, and men loved darkness rather than light, because their deeds were evil. 20
For everyone practicing evil hates the light and does not come to the light, lest his deeds should be exposed.
21But he who does the truth comes to the light, that his deeds may be clearly seen, that they have been done in God.”
And there is it once again... you do not agree, you have CDS!
