Throughout His time on earth, Christ is almost universally misunderstood. He speaks with an authority that other rabbis do not have, so His teachings are challenged. He accomplishes miracles that other men of God cannot do, so His power is challenged. He behaves as one who is “under the law,” as no one else does; and “over the law” as no one else can, so His conduct is challenged. Both the antagonists and advocates of Christ consistently and reliably misunderstand His Person, purpose and plan.
“Eloi, Eloi, lema sabachthani” are the only words Matthew and Mark record Jesus speaking from the cross. Just like much of the rest of His life, the dying words of Christ were misunderstood. One man, on hearing Christ speak, offered Him sour wine. Perhaps this was to momentarily revive Jesus, to clear His throat so that He might more clearly explain Himself.
There need not be ambiguity in the words or work of the Father or the Son. Any uncertainty, misunderstanding or confusion we may have about the will of God, the word of God or the significance of the Lord Jesus Christ is not because God did not speak clearly enough.
