1 John 3:16-20 (New International Version)

 ¹⁶This is how we know what love is: Jesus Christ laid down his life for us. And we ought to lay down our lives for our brothers. ¹⁷If anyone has material possessions and sees his brother in need but has no pity on him, how can the love of God be in him? ¹⁸Dear children, let us not love with words or tongue but with actions and in truth. ¹⁹This then is how we know that we belong to the truth, and how we set our hearts at rest in his presence ²⁰whenever our hearts condemn us. For God is greater than our hearts, and he knows everything.
