1 John 5:13-15 New International Version (NIV)

13 I write these things to you who believe in the name of the Son of Godso that you may know that you have eternal life. 14 This is the confidencewe have in approaching God: that if we ask anything according to his will, he hears us. 15 And if we know that he hears us—whatever we ask—we know that we have what we asked of him.
