29 Peter declared, "Even if all fall away, I will not." 30 "Truly I tell you," Jesus answered, "today-yes, tonight-before the rooster crows twice you yourself will disown me three times." 31 But Peter insisted emphatically, "Even if I have to die with you, I will never disown you." And all the others said the same.
31 "Simon, Simon, Satan has asked to sift all of you as wheat. 32 But I have prayed for you, Simon, that your faith may not fail. And when you have turned back, strengthen your brothers." 33 But he replied, "Lord, I am ready to go with you to prison and to death." 34 Jesus answered, "I tell you, Peter, before the rooster crows today, you will deny three times that you know me."
(Read Luke 22:21-38)
How unbecoming is the worldly ambition of being the greatest, to the character of a follower of Jesus, who took upon him the form of a servant, and humbled himself to the death of the cross! In the way to eternal happiness, we must expect to be assaulted and sifted by Satan. If he cannot destroy, he will try to disgrace or distress us. Nothing more certainly forebodes a fall, in a professed follower of Christ, than self-confidence, with disregard to warnings, and contempt of danger. Unless we watch and pray always, we may be drawn in the course of the day into those sins which we were in the morning most resolved against. If believers were left to themselves, they would fall; but they are kept by the power of God, and the prayer of Christ. Our Lord gave notice of a very great change of circumstances now approaching. The disciples must not expect that their friends would be kind to them as they had been. Therefore, he that has a purse, let him take it, for he may need it. They must now expect that their enemies would be more fierce than they had been, and they would need weapons. At the time the apostles understood Christ to mean real weapons, but he spake only of the weapons of the spiritual warfare. The sword of the Spirit is the sword with which the disciples of Christ must furnish themselves.

Commentary on Mark 14:22-31
(Read Mark 14:22-31)
The Lord's supper is food for the soul, therefore a very little of that which is for the body, as much as will serve for a sign, is enough. It was instituted by the example and the practice of our Master, to remain in force till his second coming. It was instituted with blessing and giving of thanks, to be a memorial of Christ's death. Frequent mention is made of his precious blood, as the price of our redemption. How comfortable is this to poor repenting sinners, that the blood of Christ is shed for many! If for many, why not for me? It was a sign of the conveyance of the benefits purchased for us by his death. Apply the doctrine of Christ crucified to yourselves; let it be meat and drink to your souls, strengthening and refreshing your spiritual life. It was to be an earnest and foretaste of the happiness of heaven, and thereby to put us out of taste for the pleasures and delights of sense. Every one that has tasted spiritual delights, straightway desires eternal ones. Though the great Shepherd passed through his sufferings without one false step, yet his followers often have been scattered by the small measure of sufferings allotted to them. How very apt we are to think well of ourselves, and to trust our own hearts! It was ill done of Peter thus to answer his Master, and not with fear and trembling. Lord, give me grace to keep me from denying thee.
