Ash Wednesday is that moveable feast where we encounter repentance and enter into a time of self-denial where we can focus on repenting before God. Repentance is the idea to stop our counter-God behavior and turn back to our Father. We came from perfection. A perfect created world, a perfect garden, with perfect animals and perfect people. Then sin entered the world and all of creation became temporary and darkness took a foothold. God's love and story is about redeeming that darkness and imperfection back to final perfection when His son returns. We will be part of the perfection on that day. But until then we fast, we pray, we confess, we repent, and we long for the return. We will one day return to the dust. Of course that isn't the final story. That dust will be re-imaged into a perfect creation again.
Ash Wednesday is that day when we realize our imperfections and repent of our God-lacking lives and come back to where we should always be. This is the day when we celebrate a God who welcomes us back from a prodigal life. Here is a traditional Ash Wednesday Psalm
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 you are right in your verdict
and justified when you judge.
5 Surely I was sinful at birth,
sinful from the time my mother conceived me.
6 Yet you desired faithfulness even in the womb;
you taught me wisdom in that secret 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,
so that sinners will turn back to you.
14 Deliver me from the guilt of bloodshed, O God,
you who are God my Savior,
and my tongue will sing of your righteousness.
15 Open my lips, Lord,
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 My sacrifice, O God, is[b] a broken spirit;
a broken and contrite heart
you, God, will not despise.
18 May it please you to prosper Zion,
to build up the walls of Jerusalem.
19 Then you will delight in the sacrifices of the righteous,
in burnt offerings offered whole;
then bulls will be offered on your altar.
