In a nutshell, keep the Commandments:

Lutero:

What is the Gospel?

In a nutshell, keep the Commandments:John 14:21

King James Version (KJV)
²¹ He that hath my commandments, and keepeth them, he it is that loveth me: and he that loveth me shall be loved of my Father, and I will love him, and will manifest myself to him.

But, you will deny that, I'm sure. Even though Christ Himself commands it.

2 Timothy 4:3

King James Version (KJV)
³ For the time will come when they will not endure sound doctrine; but after their own lusts shall they heap to themselves teachers, having itching ears;

Sincerely,

De Maria
