¹⁷ You therefore, beloved, ^(A)knowing this beforehand, ^(B)take care that you are not carried away with the error of lawless people and lose your own stability.

Jesus Foretells Peter's Denial

^30 (A)And when they had sung a hymn, ^(B)they went out to ^(C)the Mount of Olives. ³¹ Then Jesus said to them, “You will all fall away because of me this night. For it is written, ‘I will ^(D)strike the shepherd, and the sheep of the flock will be scattered.’ ³² But after I am raised up, ^(E)I will go before you to Galilee.” ^33 (F)Peter answered him, “Though they all fall away because of you, I will never fall away.” ^34 (G)Jesus said to him, “Truly, I tell you, this very night, ^(H)before the rooster crows, you will deny me three times.” ^35 (I)Peter said to him, “Even if I must die with you, I will not deny you!” And all the disciples said the same.

The Whole Armor of God

¹⁰ Finally, ^(A)be strong in the Lord and in ^(B)the strength of his might. ^11 (C)Put on ^(D)the whole armor of God, that you may be able to stand against ^(E)the schemes of the devil. ¹² For ^(F)we do not wrestle against flesh and blood, but against ^(G)the rulers, against the authorities, against ^(H)the cosmic powers over ^(I)this present darkness, against ^(J)the spiritual forces of evil ^(K)in the heavenly places. ¹³ Therefore ^(L)take up the whole armor of God, that you may be able to withstand in ^(M)the evil day, and having done all, to stand firm. ¹⁴ Stand therefore, ^(N)having fastened on the belt of truth, and ^(O)having put on the breastplate of righteousness, ¹⁵ and, ^(P)as shoes for your feet, having put on the readiness given by the gospel of peace. ¹⁶ In all circumstances take up ^(Q)the shield of faith, with which you can extinguish all ^(R)the flaming darts of ^(S)the evil one; ¹⁷ and take ^(T)the helmet of salvation, and ^(U)the sword of the Spirit, which is the word of God, ¹⁸ praying ^(V)at all times ^(W)in the Spirit, ^(X)with all prayer and supplication. To that end, ^(Y)keep alert with all perseverance, making ^(Z)supplication for all the saints, ¹⁹ and ^(AA)also for me, that words may be given to me in opening my mouth ^(AB)boldly to proclaim ^(AC)the mystery of the gospel, ²⁰ for which I ^(AD)am an ambassador ^(AE)in chains, that I may declare it boldly, as I ought to speak.

¹⁵ Do your best to present yourself to God as one approved,^[a] a worker ^(A)who has no need to be ashamed, rightly handling the word of truth.

Warning Against Neglecting Salvation

2 Therefore we must pay much closer attention to what we have heard, lest we drift away from it.
