1 John 1:5-10
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 yet walk in the darkness, we lie and do not live by 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 has no place in our lives"

Psalm 119:9-16
9 How can a young man cleanse his way?
By taking heed according to Your word.
10 With my whole heart I have sought You;
Oh, let me not wander from Your commandments!
11 Your word I have hidden in my heart,
That I might not sin against You.
12 Blessed are You, O LORD!
Teach me Your statutes.
13 With my lips I have declared
All the judgments of Your mouth.
14 I have rejoiced in the way of Your testimonies,
As much as in all riches.
15 I will meditate on Your precepts,
And contemplate Your ways.
16 I will delight myself in Your statutes;
I will not forget Your word.
