"For God so loved the world that He gave His only begotten Son, that whoever believes in Him should not perish but have life eternal."..
That if you confess with your mouth the Lord Jesus and believe in your heart that God has raised Him from the dead, you will be saved...
Moreover, brethren, I declare to you the gospel which I preached to you, which also you received and in which you stand, by which also you are saved, if you hold fast that word which I preached to you—unless you believed in vain. For I delivered to you first of all that which I also received:
That Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again the third day according to the Scriptures.
