Since we know there is a judgment coming, we need to be people of peace, spotless and blameless, and understanding the patience of God as salvation (3:10-15). 3:15-16 give us a bit of information. First of all we are told that Paul’s writings, and by extension those of all of the New Testament writers, are Scripture, on a par with those of the Old Testament. Further, Peter has a hard time understanding some of what Paul says. So if Peter found Paul to be deep we should not feel bad when we cannot understand everything he has to say either. But this should not keep us from reading all of Paul, and praying for understanding.
1 John: The letters of John are unique in that in them he does not list himself as the sender as do Paul, Peter, James, and Jude. In the second and third he lists himself merely as “the elder” but here there is nothing. He also begins his writing in this letter in the first person (we/us) before shifting to the third person.
In 1:5-8 we should be reminded of John’s usage of the imagery of light in his Gospel, especially the ninth chapter (the man born blind).
“The one who says ‘I have come to know Him,’ and does not keep His commandments is a liar” (2:4).
Note his wording in 2:18. He speaks of MANY antichrists, not merely “THE” as do many today. The word merely means one who is opposed to Christ (see also 4:1-3). He also says that it was then (now to him) “the last hour.” Remember how John used the word “hour” throughout his Gospel (“his hour had not yet come,” John 2:4; 7:30; 8:20).
Although he does not speak of one’s fruit as does Paul, John uses the same imagery when he speaks of those who are righteous practicing righteousness and those who practice sin being of the devil (3:8).
“Whatever we ask we receive from Him because we keep His commandment” (3:22). “His commandment is that we believe in Christ and love one another” (3:23).
Pay close attention to 4:4-5 also.
Proverbs: He who is righteous works diligently and is greatly blessed. But the fool works lazily and sloppily when he does work and does much malicious mischief, so God punishes him.
