There is plenty of debate on "works".
We are not saved by our own works, that's for sure. But are saved to work the works of God.
Saved by grace. True. Unmerited favor. It's because he loves us that he sends preachers that preach the plan of salvation.
Gotta hear the God ordained preacher? Yes. Some effort involved in that? Yes.
Gotta believe what that preacher says? Yes. (turning toward God, which is repentance, is a product of belief)
Gotta call on the name of the Lord? Yes. Some effort involved in that? Yes.
Believing on the Lord Jesus Christ is not only about what he did, but also what he said. ("..whosoever heareth these sayings of mine..")
Here's some of the important things he said:
John 3:3-8 "..Except a man be born again, he cannot enter into the kingdom of God", "..Except a man be born of the water and of the Spirit, he cannot enter into the kingdom of God". "..Marvel not that I said unto thee, Ye must be born again". "thou hearest the sound thereof....so is every one that is born of the Spirit".
And John 7:38,39 "He that believeth on me as the scripture hath said, out of his belly shall flow rivers of living water" (But this spake he of the Spirit which they that believe on him should receive: for the Holy Ghost was not yet given; because that Jesus was not yet glorified.)
And there's always the parable of the talents and the story about separating the sheep from the goats....no matter what, he who sits on his duff and doesn't do the Lord's work has let his Lord down...
