2 John 1
John writes about those who have “come to know the truth” and that he is rejoicing to see some young family members “walking in the truth” (vv. 1, 4). This “truth” is not some list of doctrines or deep theology but a simple commandment: “that we love one another” (v. 5). Sometimes we can overcomplicate the “truth.” Now don’t misunderstand John; the truth in Scripture is very deep and has many levels. It is not merely comprised of this one commandment. We might say that whatever Scripture reveals on any subject can be constituted as “truth.”
As John wrote about in his previous letter (cf. 1 John 5), biblically speaking love is not predominantly this passionate emotion of desire as some might think of it. Rather, the love that John is talking about is intricately bound together with obedience. And therefore, this is why he says, “And this is love: that we walk according to his commandments” (v. 6).
Why is this so important to John that he is reiterating it again here in his 2nd letter? The reason is likely part of his subsequent warning about the “many deceivers” who are in the world (v. 7). There are many forces at work in the world vying for our attention and our devotion. John raises the danger about these “deceivers” and how they can lead someone astray from the truth, for he declares that “everyone who goes too far and does not remain in the teaching about Christ does not have God (v. 9).
We need to be aware and watch ourselves concerning those who do not “bring the teaching about Christ.” John is very stern about not entertaining deceivers in our homes. The adversary works in subtle ways and sometimes these deceptive influences can come from unlikely places and people who may not even be consciously or intentionally opposing God and the teaching about Christ, but nonetheless are stealthily subverting the message of the good news with criticism, skepticism, or mockery.
Let us be careful to recognize these evil works and not lose our focus on living according to God’s commandments.
