<p>3:20 <em>Because if our heart condemns us, God is greater than our heart, and knows all things</em>- The preceding verse has spoken of being able to assure our hearts before the Lord at judgment day, if we have lived in love. The context here in :20 therefore specifically refers to the question of whether or not we can say we live in love. If it does, then God is greater than our various feelings of bad conscience concerning those we do not love. He knows all things- if we know we have not lived in love, then this will be symptomatic of yet more sins, which He knows all about. The same Greek words for &quot;knows all things&quot; are used about the Lord Jesus knowing all things that are in men (Jn. 2:24).</p>
