With the example of Christ before them the readers are to show more constancy under their own sufferings. They are to think of Him whose life was so thwarted by wicked men, and thus nerve themselves to strength and patience (Hebrews 12:3). What is their struggle compared to that of Jesus? They have not yet been called on to venture their lives in the battle for righteousness, and under such sufferings as have been laid on them they have given way, forgetting that affliction is a chastisement which God imposes on His children with a loving purpose. Thus considered, it is a proof to us that we are really God's children, and if we are spared it, we may well doubt whether He acknowledges us (Hebrews 12:4-8). We did not rebel against our earthly fathers when they disciplined us; can we not believe that through the discipline we receive from our heavenly Father we shall rise to a truer life (Hebrews 12:9)? Our earthly fathers could train us only for the short period of youth, and sometimes their judgment was mistaken. God, on the other hand, unfailingly seeks our highest welfare, and disciplines us all our life long that we may grow into moral likeness to Himself (Hebrews 12:10). Suffering while it lasts is no doubt hard to bear, but the painful process has its outcome in that righteousness which alone brings peace. Let us march on, therefore, with new energy, and let those who are strong try so to direct their steps that the weaker may not be led astray and exhausted, but may be cheered on to a more vigorous advance.
Hebrews 12:3. against themselves: implies that in rejecting Christ they had defeated their own welfare; but the marginal reading, against Himself, is simpler and better.
Hebrews 12:13 for your feet: better, with your feet. Addressing the more capable and intelligent, the writer bids them think of themselves as pioneers, making a path for their halting comrades.
