Where does Jesus say that in the goats and sheep parable? Where does Jesus preach salvation through faith in His sacrifice alone anywhere in The Bible? Don't quote me Paul or any apostle. Give me a verse from Jesus Himself.
47“For this reason I say to you, her sins, which are many, have been forgiven, for she loved much; but he who is forgiven little, loves little.” 48Then He said to her, “Your sins have been forgiven.” 49Those who were reclining at the table with Him began to say to themselves, “Who is this man who even forgives sins?” 50And He said to the woman, “Your faith has saved you; go in peace.”
Her love for Jesus displayed in her service for Him was the evidence that she was saved through faith in God's forgiveness. She will stand in the Judgment as a sheep and enter into the kingdom not because her service for Jesus earned that salvation but because her service for Jesus is the proof of her having received the forgiveness of God in salvation.
