Peter succumbed to his physical weariness at a time when alertness was needed. Bro. Jeff explains the spiritual need Jesus expressed to Peter, and how that applies to us today.
Matthew 26:39-41 (KJV)
39 And he went a little farther, and fell on his face, and prayed, saying, O my Father, if it be possible, let this cup pass from me: nevertheless not as I will, but as thou wilt.
40 And he cometh unto the disciples, and findeth them asleep, and saith unto Peter, What, could ye not watch with me one hour?
41 Watch and pray, that ye enter not into temptation: the spirit indeed is willing, but the flesh is weak.
5 Let this mind be in you, which was also in Christ Jesus:
6 Who, being in the form of God, thought it not robbery to be equal with God:
7 But made himself of no reputation, and took upon him the form of a servant, and was made in the likeness of men:
8 And being found in fashion as a man, he humbled himself, and became obedient unto death, even the death of the cross.
9 After this manner therefore pray ye: Our Father which art in heaven, Hallowed be thy name.
10 Thy kingdom come, Thy will be done in earth, as it is in heaven.
1 Peter 5:8
8 Be sober, be vigilant; because your adversary the devil, as a roaring lion, walketh about, seeking whom he may devour:
2 Continue in prayer, and watch in the same with thanksgiving;
31 And the Lord said, Simon, Simon, behold, Satan hath desired to have you, that he may sift you as wheat:
32 But I have prayed for thee, that thy faith fail not: and when thou art converted, strengthen thy brethren.
13 And lead us not into temptation, but deliver us from evil: For thine is the kingdom, and the power, and the glory, for ever. Amen.
10 Finally, my brethren, be strong in the Lord, and in the power of his might.
11 Put on the whole armour of God, that ye may be able to stand against the wiles of the devil.
12 For we wrestle not against flesh and blood, but against principalities, against powers, against the rulers of the darkness of this world, against spiritual wickedness in high places.
13 Wherefore take unto you the whole armour of God, that ye may be able to withstand in the evil day, and having done all, to stand.
14 Stand therefore, having your loins girt about with truth, and having on the breastplate of righteousness;
15 And your feet shod with the preparation of the gospel of peace;
16 Above all, taking the shield of faith, wherewith ye shall be able to quench all the fiery darts of the wicked.
17 And take the helmet of salvation, and the sword of the Spirit, which is the word of God:
18 Praying always with all prayer and supplication in the Spirit, and watching thereunto with all perseverance and supplication for all saints;
Galatians 5:16-17, 24-25
16 This I say then, Walk in the Spirit, and ye shall not fulfil the lust of the flesh.
17 For the flesh lusteth against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
24 And they that are Christ’s have crucified the flesh with the affections and lusts.
25 If we live in the Spirit, let us also walk in the Spirit.
