FAITH A DOCTRINE OF CHRIST.
The first and principal doctrine taught by Christ was faith.
"God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life." (John 3: 16).
Our Savior knew that if people truly had abiding faith in Him they would follow Him. They would love Him and obey all His teachings.
"He that believeth on me, the works that I do shall he do also." (John 14: 13).
"If a man love me, he will keep my words." (John 14: 23).
