This Sunday - the second Sunday of Advent 2010 - we are preparing to take the Lord's Supper together. It is a special and sacred time when we remember what the church has been remembering for nearly 2,000 years.
We will remember and rejoice in the life, death and resurrection of our Savior. We will remember our hope. There is a stern warning, though, as we approach the Lord's table. Paul passes it along in 1 Corinthians 11,
Whoever, therefore, eats the bread or drinks the cup of the Lord in an unworthy manner will be guilty concerning the body and blood of the Lord.  Let a person examine himself, then, and so eat of the bread and drink of the cup.  For anyone who eats and drinks without discerning the body eats and drinks judgment on himself.  That is why many of you are weak and ill, and some have died.  But if we judged ourselves truly, we would not be judged.  But when we are judged by the Lord, we are disciplined so that we may not be condemned along with the world.
(1 Corinthians 11:27-32 ESV)
As we prepare our hearts to take of the Lord's Supper may we pray as David did in Psalm 139,
 Search me, O God, and know my heart!
Try me and know my thoughts!
 And see if there be any grievous way in me,
and lead me in the way everlasting!
(Psalm 139:23-24 ESV)
As we search our hearts may we also have courage to take action. Such as David did in Psalm 51,
Have mercy on me, O God,
according to your steadfast love;
according to your abundant mercy
blot out my transgressions.
 Wash me thoroughly from my iniquity,
and cleanse me from my sin!
 For I know my transgressions,
and my sin is ever before me.
 Against you, you only, have I sinned
and done what is evil in your sight,
so that you may be justified in your words
and blameless in your judgment.
 Behold, I was brought forth in iniquity,
and in sin did my mother conceive me.
 Behold, you delight in truth in the inward being,
and you teach me wisdom in the secret heart.
 Purge me with hyssop, and I shall be clean;
wash me, and I shall be whiter than snow.
 Let me hear joy and gladness;
let the bones that you have broken rejoice.
 Hide your face from my sins,
and blot out all my iniquities.
 Create in me a clean heart, O God,
and renew a right spirit within me.
 Cast me not away from your presence,
and take not your Holy Spirit from me.
 Restore to me the joy of your salvation,
and uphold me with a willing spirit.
 Then I will teach transgressors your ways,
and sinners will return to you.
 Deliver me from bloodguiltiness, O God,
O God of my salvation,
and my tongue will sing aloud of your righteousness.
 O Lord, open my lips,
and my mouth will declare your praise.
 For you will not delight in sacrifice, or I would give it;
you will not be pleased with a burnt offering.
 The sacrifices of God are a broken spirit;
a broken and contrite heart, O God, you will not despise.
 Do good to Zion in your good pleasure;
build up the walls of Jerusalem;
 then will you delight in right sacrifices,
in burnt offerings and whole burnt offerings;
then bulls will be offered on your altar.
(Psalm 51 ESV)
May we do the work of preparing our hearts as we approach the Lord's table this Lord's Day.
