As a witness for Christ, John entered into no controversy, no wearisome contention. He declared what he knew, what he had seen and heard. He had been intimately associated with Christ, had listened to His teachings, had witnessed His mighty miracles. Few could see the beauties of Christ's character as John saw them. For him the darkness had passed away; on him the true light was shining. His testimony in regard to the Saviour's life and death was clear and forcible. Out of the abundance of a heart overflowing with love for the Saviour he spoke; and no power could stay his words.

Som vidne for Kristus indlod Johannes sig ikke i nogen ordstrid eller trættende diskussion. Han forkyndte det, han kendte, det, han havde set og hørt. Han havde levet i nær forbindelse med Kristus, havde lyttet til hans lære, havde været vidne til hans vældige undergerninger. Kun få kunne se skønheden i Kristi karakter, som Johannes så den. For ham var mørket veget bort, over ham strålede det sande lys. Hans vidnesbyrd om Frelserens liv og død var klart og stærkt. Han talte af sit hjertes overflod, hans hjerte strømmede over af kærlighed til Frelseren og ingen magt kunne standse ham.
