We can believe that Jesus is greater than any earthly competition for his affection. We can say that his glory should eclipse all others in our life. We can sing of our love for him, our devotion to him, our passion for him.
But while we believe, we forget.
We get into the busyness of our day, and we forget. We get into the heat of a trial, and we forget. We wrestle with the same old sins, and we forget.
What we know to be true, we forget to be true.
