Isaiah 59:2
2But your iniquities have separated you from your God; your sins have hidden his face from you, so that he will not hear.
Romans 3:22,23
22This righteousness from God comes through faith in Jesus Christ to all who believe. There is no difference, 23for all have sinned and fall short of the glory of God.
Psalm 51
1 Have mercy on me, O God, according to your unfailing love; according to your great compassion blot out my transgressions. 2 Wash away all my iniquity and cleanse me from my sin. 3 For I know my transgressions, and my sin is always before me. 4 Against you, you only, have I sinned and done what is evil in your sight, so that you are proved right when you speak and justified when you judge. 5 Surely I was sinful at birth, sinful from the time my mother conceived me. 6 Surely you desire truth in the inner parts; you teach me wisdom in the inmost place. 7 Cleanse me with hyssop, and I will be clean; wash me, and I will be whiter than snow. 8 Let me hear joy and gladness; let the bones you have crushed rejoice. 9 Hide your face from my sins and blot out all my iniquity. 10 Create in me a pure heart, O God, and renew a steadfast spirit within me. 11 Do not cast me from your presence or take your Holy Spirit from me. 12 Restore to me the joy of your salvation and grant me a willing spirit, to sustain me. 13 Then I will teach transgressors your ways, and sinners will turn back to you. 14 Save me from bloodguilt, O God, the God who saves me, and my tongue will sing of your righteousness. 15O Lord, open my lips, and my mouth will declare your praise. 16 You do not delight in sacrifice, or I would bring it; you do not take pleasure in burnt offerings. 17 The sacrifices of God are a broken spirit; a broken and contrite heart, O God, you will not despise. 18 In your good pleasure make Zion prosper; build up the walls of Jerusalem. 19 Then there will be righteous sacrifices, whole burnt offerings to delight you; then bulls will be offered on your altar.
Psalm 25:4-11
4 Show me your ways, O LORD, teach me your paths; 5 guide me in your truth and teach me, for you are God my Saviour, and my hope is in you all day long. 6 Remember, O LORD, your great mercy and love, for they are from of old. 7 Remember not the sins of my youth and my rebellious ways; according to your love remember me, for you are good, O LORD. 8 Good and upright is the LORD; therefore he instructs sinners in his ways. 9 He guides the humble in what is right and teaches them his way. 10 All the ways of the LORD are loving and faithful for those who keep the demands of his covenant. 11 For the sake of your name, O LORD, forgive my iniquity, though it is great.
1 John 1:5-10
5This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. 6If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by the truth. 7But 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. 8If we claim to be without sin, we deceive ourselves and the truth is not in us. 9If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness. 10If we claim we have not sinned, we make him out to be a liar and his word has no place in our lives.
