New Defender's Study Bible Notes
3:14 passed from death unto life. Here is another test for knowing whether we are truly saved, and have “passed from death unto life” (John 5:24). See also I John 2:3,5; 3:24; 5:2,13.
3:14 love the brethren. John gives three characteristics of true love for our brethren: doing righteousness (I John 3:10); willingness to die for them (I John 3:16); willingness to share our possessions with them” (I John 3:17).
