Hebrews 9:11 "But Christ came as High Priest of the good things to come, with the greater and more perfect tabernacle not made with hands, that is, not of this creation. 12 Not with the blood of goats and calves, but with His own blood He entered the Most Holy Place once for all, having obtained eternal redemption. 13 For if the blood of bulls and goats and the ashes of a heifer, sprinkling the unclean, sanctifies for the purifying of the flesh, 14 how much more shall the blood of Christ, who through the eternal Spirit offered Himself without spot to God, cleanse your conscience from dead works to serve the living God?
15 And for this reason He is the Mediator of the new covenant, by means of death, for the redemption of the transgressions under the first covenant, that those who are called may receive the promise of the eternal inheritance. 16 For where there is a testament, there must also of necessity be the death of the testator. 17 For a testament is in force after men are dead, since it has no power at all while the testator lives. 18 Therefore not even the first covenant was dedicated without blood. 19 For when Moses had spoken every precept to all the people according to the law, he took the blood of calves and goats, with water, scarlet wool, and hyssop, and sprinkled both the book itself and all the people, 20 saying, "This is the blood of the covenant which God has commanded you." 21 Then likewise he sprinkled with blood both the tabernacle and all the vessels of the ministry. 22 And according to the law almost all things are purified with blood, and without shedding of blood there is no remission.
23 Therefore it was necessary that the copies of the things in the heavens should be purified with these, but the heavenly things themselves with better sacrifices than these. 24 For Christ has not entered the holy places made with hands, which are copies of the true, but into heaven itself, now to appear in the presence of God for us; 25 not that He should offer Himself often, as the high priest enters the Most Holy Place every year with blood of another–– 26 He then would have had to suffer often since the foundation of the world; but now, once at the end of the ages, He has appeared to put away sin by the sacrifice of Himself. 27 And as it is appointed for men to die once, but after this the judgment, 28 so Christ was offered once to bear the sins of many. To those who eagerly wait for Him He will appear a second time, apart from sin, for salvation."
A commentary on these verses state a truth that I cannot say any better: "The blood of Christ is of infinite value; its power is sufficient to cleanse all the sins of all the people who have ever lived, all the people who are now living, and all the people who will ever live. Of course, its power is applicable only to those who come to Him by faith. But its cleansing potential is unlimited". 
We came this morning to worship God, who through the Lord Jesus Christ, offered the perfect sacrifice, Christ’s body and blood to cleanse us from all sin. We come now to the table, where the symbols of this sacrifice sit, symbols in both name and object, a loaf of bread to remind us that He is the bread of life, that was broken for us, and wine, as we read in Matthew 26: 27 Then He took the cup, and gave thanks, and gave it to them, saying, "Drink from it, all of you. 28 "For this is My blood of the new covenant, which is shed for many for the remission of sins."
As we take these symbols, we need to have clean hearts, sins confessed, made right with God: though God’s sacrifice was once for all, we need to continue to reflect on our lives, our relationships with others, and ask ourselves if we are walking with God, through the Holy Spirit in holiness. Being humans that we are, backsliding is an easy pathway, but through God, our salvation stands, praise the Lord, and all one needs to do is reconnect, turn our lives back to God, with repentance, with confession, with a heart glad for the blood of Christ. This is blood that has saved us from our sins, is saving us, and will save us. So as we prepare our hearts for this memorial, we, as stated in 1 Corinthians: "11:28 But let a man examine himself, and so let him eat of the bread and drink of the cup. 29 For he who eats and drinks in an unworthy manner eats and drinks judgment to himself,"
Therefore, even now we can pray with the Psalmist, as Jesus taught us, and as he gave us the perfect example: Psalm 139 " Search me, O God, and know my heart; Try me, and know my anxieties; 24 And see if there is any wicked way in me, And lead me in the way everlasting." 'Forgive us our sins as we forgive those that sin against us", and he will respond 'Assuredly, I say to you, today you will be with Me in Paradise." Then with hearts free to worship, we remember the Lord Jesus Christ, his death and sacrifice, and the gift of salvation through God’s Grace. As we take these emblems, may worship in our hearts with the lines from a verse of an old hymn:
"Man of Sorrows", what a name;
For the Son of God who came;
Ruined sinners to reclaim;…
Bearing shame and scoffing rude,
In my place condemned He stood;
Sealed my pardon with His blood; …
When He comes, our glorious King,
All His ransomed home to bring;
Then anew this song we’ll sing,
Hallelujah, what a Saviour.
