It is a good and faithful instinct to desire that nothing be added to the Word of God, and that truth be spoken concerning the sufferings of our Lord. The Scriptures have not given us a number for the stripes laid upon His blessed back, and we must not invent what the Holy Ghost has not revealed.
What is revealed is of far greater weight and glory. The Apostle does not give us details of Christ's sufferings, but he lets us, for a moment, look into this condensation of them, "Christ also has once suffered." When we ask when did Christ suffer, we may truly reply, when was there that He did not suffer while He walked this earth. Yet we are not to depreciate the bodily sufferings of Christ, though it has been well said that the soul sufferings of Christ were the soul of His sufferings. It was not merely the scourge of Rome, but the bearing of sin itself, for He suffered for sins not His own, the just for the unjust, that He might bring us to God.
We need not a tradition of six hundred lashes to make His sacrifice sufficient, for He was made a perfect Saviour through suffering. He was not made perfect in character by His suffering, for He always was perfect, perfect God and perfect man, but He was made officially perfect, perfect as the Captain of our salvation through His sufferings. In all our afflictions He was afflicted, and there is no shape of human sorrow that is new to Him.
Therefore let us rest not upon uncertain numbers, but upon the certain Word, that Christ was bound that we might be free, that He was made sin for us that we might be made the righteousness of God in Him, and that He poured out His life's blood upon the cross for sinners who trust Him.
My prayer for you is that the Lord will give you a love for His truth as it is in Jesus, that you may buy the truth and sell it not, and that you may know more deeply the sympathy of Him who was tempted and suffered, that He might succour them that are tempted. May you be kept from every false addition to Scripture, and may you find your whole confidence not in a count of stripes, but in the finished work of the Redeemer, believing on the Lord Jesus Christ and so being saved.
