Cleansing our sins again and again

Last Sunday when I was at church, my son (Andrew, 1.5 years old), want to come out of church and want to be outside. There was one tree with small red fruits (common in Karnataka). The fruits fell down on the ground he will pick and squeeze. His figures will become dirty. Then he will come to me to clean his hand with my kerchief. Every time he made his hand dirty, he will come to me and ask me to clean. Third time when he came to me, a thought came to my mind. This is the same way I (we) approach Jesus each time when we do sin and approach for confession. That day my son came to me around 7 times. Since other thought already came to my mind I did not got angry :-)
