2 Peter 1:9-10

9But some people do not live in these good ways. They do not think that these things are important. They are like blind people. They cannot really see anything properly. They have forgotten that God has made them clean from all the sins that they did in past times.

10So, my friends, try very much to live in a way that pleases God. God has chosen you to be his own people. Show that you really do belong to him! If you do these things, you will never turn away from God.
