1 John 1:5-10 (NIV)
Light and Darkness, Sin and Forgiveness
5 This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. 6 If we claim to have fellowship with him and yet walk in the darkness, we lie and do not live out the truth. 7 But if we walk in the light, as he is in the light, we have fellowship with one another, and the blood of Jesus, his Son, purifies us from all sin.
8 If we claim to be without sin, we deceive ourselves and the truth is not in us. 9 If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10 If we claim we have not sinned, we make him out to be a liar and his word is not in us.
1 John 2:1-2 (NIV)
2 My dear children, I write this to you so that you will not sin. But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One. 2 He is the atoning sacrifice for our sins, and not only for ours but also for the sins of the whole world.
Luke 17:11-19 (NIV)
Jesus Heals Ten Men With Leprosy
11 Now on his way to Jerusalem, Jesus traveled along the border between Samaria and Galilee. 12 As he was going into a village, ten men who had leprosy[a] met him. They stood at a distance 13 and called out in a loud voice, “Jesus, Master, have pity on us!”
14 When he saw them, he said, “Go, show yourselves to the priests.” And as they went, they were cleansed.
15 One of them, when he saw he was healed, came back, praising God in a loud voice. 16 He threw himself at Jesus’ feet and thanked him—and he was a Samaritan.
17 Jesus asked, “Were not all ten cleansed? Where are the other nine? 18 Has no one returned to give praise to God except this foreigner?” 19 Then he said to him, “Rise and go; your faith has made you well.”
