Where to find scriptural help, when backsliding:
1 John 1:4-9
We write this to make our joy complete. This is the message we have heard from him and declare to you: God is light; in him there is no darkness at all. If we claim to have fellowship with him yet walk in the darkness, we lie and do not live by the truth. 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. If we claim to be without sin, we deceive ourselves and the truth is not in us. If we confess our sins, he is faithful and just and will forgive us our sins and purify us from all unrighteousness.
Have mercy on me, O God,
according to your unfailing love;
according to your great compassion
blot out my transgressions.
Wash away all my iniquity
and cleanse me from my sin.
For I know my transgressions,
and my sin is always before me.
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.
Surely I was sinful at birth,
sinful from the time my mother conceived me.
Surely you desire truth in the inner parts,
you teach me wisdom in the inmost place.
Cleanse me with hyssop, and I will be clean;
wash me, and I will be whiter than snow.
Let me hear joy and gladness;
let the bones you have crushed rejoice.
Hide your face from my sins
and blot out all my iniquity.
Create in me a pure heart, O God,
and renew a steadfast spirit within me.
Do not cast me from your presence
or take your Holy Spirit from me.
Restore to me the joy of your salvation
and grant me a willing spirit, to sustain me.
Then I will teach transgressors your ways,
and sinners will turn back to you.
Save me from bloodguilt, O God,
the God who saves me,
and my tongue will sing of your righteousness.
O Lord, open my lips,
and my mouth will declare your praise.
You do not delight in sacrifice, or I would bring it;
you do not take pleasure in burnt offerings.
The sacrifices of God are a broken spirit;
a broken and contrite heart, O God, you will not despise.
In your good pleasure make Zion prosper;
build up the walls of Jerusalem.
Then there will be righteous sacrifices,
whole burnt offerings to delight you;
then bulls will be offered on your altar.
Lord our strength, the battle of good and evil rages within and around us, and our ancient foe tempts us with his deceits and empty promises. Keep us steadfast in your Word, and when we fall, raise us up again and restore us through your Son, Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, now and forever.(Christian Worship: Manual, First Sunday in Lent)
