If the endeavor to get back to Christ means the Synoptic Gospels to the exclusion of the fourth, or the Epistles; or the Sermon on the Mount to the exclusion of the Epistle to the Romans; or Jesus to the exclusion of His Apostles, we feel it is but half the truth. Our Lord Himself protested that His teachings were incomplete, that there was much left unsaid which would be said by the Comforter, as even He could not, because the Spirit of God speaks in the inner shrine of the soul, uttering to the inner ear, truths which no voice could speak or ear receive. Let us always remember therefore that the Gospels must be completed by the Epistles, and that the Spirit who spake in the Son, spake also in those whom the Son had prepared to be His mouthpieces to men. II. THE PARTIAL MEASURE OF HUMAN ABILITY TO KNOW.--"Ye cannot bear them now." Our Lord's reticence did not arise from ignorance, He could have said so much had He not been able to say more. All things were naked and open to His eye, but He had a tender regard for these men whom He loved. _Their bodies_ could not bear more. When the mind is strongly wrought upon, the delicate organism of the body is deeply affected. On the banks of the river Hiddekel, words of such wondrous importance were uttered to the lonely exile, that Daniel fainted, and was sick many days. "When I saw Him," says John, "I fell at His feet as dead." Flavel, on more than one occasion, asked that the excessive revelation might be stayed. Our Lord, therefore, feared that in their weakened state, torn by anxiety and sorrow, His followers would collapse if further strain were imposed upon their powers of spiritual apprehension. _Their minds_ could not bear more. The mind cannot receive more than a certain amount. After a while its eye gets weary, it ceases to receive, and even to remember. There are multitudes of cases in which, when too great a weight has been crowded on the delicate organism through which thoughts move, its balance has been upset, and it has drivelled into idiocy. Against this danger, also, our Lord guarded, for His disciples were already excited and over-strained. Their brains were so exhausted that in a few moments they would be sleeping on the cold ground of Gethsemane. Had He poured the light of the other world in full measure upon them, the tide of glory had submerged them, like spent swimmers. _Their affections_ could not bear more. Because He had spoken to them, sorrow had filled their heart, and He forbore to describe the valley of shadow through which they were still to pass, lest their hearts should break. They had hardly commenced to drink its cup: what would its dregs be? The footmen had wearied them: how would they contend with horses? The brink had terrified them: how would they do in the swellings of Jordan?
