<p>5:13- see on Mt. 16:16; Jn. 20:31; 1 Jn. 1:3.</p><p><i>I write these things to you who believe in the name of the Son of God, that you may know that you have eternal life</i>- Clearly there were some who had believed into the Name of Jesus, demonstrating it through baptism into that Name, who doubted their salvation, and whether they had in fact received the promise of &quot;eternal life&quot; as a present experience. In this we find John addressing so many of us. John has flanged out from discussing how to recognize a true Christian and thereby reject false Christians into the more personal application to ourselves. We who have believed in the Lord have received the gift of His Spirit, His life, which is an eternal life.</p>
