<p>There are many important teachings in the Bible that help us better understand the Christian faith and live more fulfilling lives. One such passage is <em>1 John 5:12</em>. In this verse, <em>John</em> explains that only those who <em>believe in Jesus Christ</em> can have eternal life.</p>
<p><strong>Having a Son to have eternal life</strong></p>
<p>According to the New Testament, only those who believe in Jesus Christ and accept Him as <em>their personal Savior</em> can expect to have eternal life. The apostle John makes a clear distinction between those who have a Son and those who do not. This refers to those who have experienced the presence and power <em>of Jesus</em> in their lives and have fully trusted Him.</p>
<p><strong>Why we need Jesus to have life</strong></p>
<p>The first man, <em>Adam</em>, sinned, and since then all people have inherited sin and are separated from God. The Bible teaches that there is no way for people to be saved on their own; they need a Savior. In the New Testament, Jesus is that salvation. Only those who believe in Him and accept His Sacrifice on the Cross can be saved and have eternal life.</p>
