O Father, how we need mercy. We sin every day. We fall short of your command to love you with all our heart and soul and mind and strength. We are lukewarm in our affections. All our motives, even at their best, are mixed. We murmur. We are anxious about tomorrow. We get angry too quickly. We desire what out not be desired. We get irritated at the very attitudes in others that we ourselves displayed five minutes before. If you do not show mercy to us, we are undone. O God, let us see the mercy of Christ and savor it for what it is. Grant us power to comprehend his love. Incline us to read and ponder the stories of the mercy of Jesus in the Gospels. Let us so admire what he did that we imitate him. But let it be much more that external imitation. Let it come from the heart where we have been broken for our sin and where we have come to cherish mercy and live by mercy and hope in mercy and long for mercy. Make the mercy of Jesus the greatest beauty of the Savior in our eyes. Let us behold, and beholding, become like him. And bend this taste for mercy outward so that we show it. Make us full of his mercy that me might show mercy. Fulfill in us the command to do justice and love mercy. Let us love showing mercy. Make it so much a part of us that it is who we are. So unite us to Christ that his mercy is our mercy, and our mercy is a presenting of Christ. He is all we have to give in the end. Glorify his mercy, Father, in our faith and in our patience. Thank you, oh, thank you, for Christ and your mercy to us in him. In his name we pray, amen.
