KNOWLEDGE OF THE GOSPEL NECESSARY TO SALVATION.
It is necessary for every individual to know for himself concerning the truth of the Gospel of Christ.
"This is life eternal, that they might know thee the only true God, and Jesus Christ, whom thou hast sent." (John 17: 3).
There is a way to get this knowledge. That way is similar to the way in which we obtain other knowledge. It is by putting works with our faith.
"Hereby we do know that we know him, if we keep his commandments." (I John 2: 3).
Faith comes by hearing, knowledge by doing. Knowledge is the result of faith.
