⁴ Whoever says, “I know him,”^(A) but does not do what he commands is a liar, and the truth is not in that person.^{(B) 5} But if anyone obeys his word,^(C) love for God^[a] is truly made complete in them.^(D) This is how we know^(E) we are in him: ⁶ Whoever claims to live in him must live as Jesus did.^(F)

⁷ Dear friends,^(G) I am not writing you a new command but an old one, which you have had since the beginning.^(H) This old command is the message you have heard. ⁸ Yet I am writing you a new command;^(I) its truth is seen in him and in you, because the darkness is passing^(J) and the true light^(K) is already shining.^(L)

⁹ Anyone who claims to be in the light but hates a brother or sister^[b](M) is still in the darkness.^(N)

¹⁴ For those who are led by the Spirit of God^(A) are the children of God.^(B)

The Armor of God

¹⁰ Finally, be strong in the Lord^(A) and in his mighty power.^{(B) 11} Put on the full armor of God,^(C) so that you can take your stand against the devil’s schemes. ¹² For our struggle is not against flesh and blood,^(D) but against the rulers, against the authorities,^(E) against the powers^(F) of this dark world and against the spiritual forces of evil in the heavenly realms.^{(G) 13} Therefore put on the full armor of God,^(H) so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand. ¹⁴ Stand firm then, with the belt of truth buckled around your waist,^(I) with the breastplate of righteousness in place,^{(J) 15} and with your feet fitted with the readiness that comes from the gospel of peace.^{(K) 16} In addition to all this, take up the shield of faith,^(L) with which you can extinguish all the flaming arrows of the evil one.^{(M) 17} Take the helmet of salvation^(N) and the sword of the Spirit,^(O) which is the word of God.^(P)

⁵ Love^(A) the Lord your God with all your heart^(B) and with all your soul and with all your strength.^(C)
