God makes salvation simple.
John 1:10-13 He was in the world, and the world was made through him, yet the world did not know him. He came to his own, and his own people did not receive him. But to all who did receive him, who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of man, but of God.
Romans 10:9-13 because, if you confess with your mouth that Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. For with the heart one believes and is justified, and with the mouth one confesses and is saved. For the Scripture says, Everyone who believes in him will not be put to shame. For there is no distinction between Jew and Greek; for the same Lord is Lord of all, bestowing his riches on all who call on him. For everyone who calls on the name of the Lord will be saved.
And Protestantism can ignore all the Biblical passages that refute their spurious claims. I have already posted these and will not repeat. While claiming “Scripture alone” they have reduced it to “only Scripture that supports ‘faith alone’.” The rest they either ignore or twist to empty it of its plain meaning.
