I. Jesus Christ died on the cross to reveal the evil nature of sin.
Not only in our age, but in every age, people have been inclined to minimize and excuse sin. There are many who deny that there is any such thing as sin. There are others who joke about sin and treat it lightly. Others tolerate and coddle sin in their own hearts and lives.
Jesus died on the cross because of our sin. Had humans not been sinners, it would not have been necessary for him to die. If sin were not something terrible, dark, and destructive, Calvary would not have been necessary.
If there had been no fear problem in the heart that causes people to depart from God and live a life of waste and ruin, then Jesus Christ died as an unrealistic idealist.

It is the testimony of the Scripture that Christ died for our sins (1 Cor. 15:3-8) For I delivered to you first of all that which I also received: that Christ died for our sins according to the Scriptures, 4 and that He was buried, and that He rose again the third day according to the Scriptures, 5 and that He was seen by Cephas, then by the twelve. 6 After that He was seen by over five hundred brethren at once, of whom the greater part remain to the present, but some have fallen asleep. 7 After that He was seen by James, then by all the apostles. 8 Then last of all He was seen by me also, as by one born out of due time.
 
(1 Peter 2:24-25) 24 who Himself bore our sins in His own body on the tree, that we, having died to sins, might live for righteousness- by whose stripes you were healed. 25 For you were like sheep going astray, but have now returned to the Shepherd and Overseer of your souls.

(1Peter3:18). For Christ also suffered once for sins, the just for the unjust, that He might bring us to God, being put to death in the flesh but made alive by the Spirit
We should let the elements of the Lord’s Supper speak to us concerning the deadly, destructive, evil nature of our sin that required the death of Jesus Christ for our deliverance and forgiveness.
II. Jesus Christ died on the cross to redeem and save us (Mark 10:45).
A. Jesus was the perfect substitute. He died to ransom us from sin (Mark 10:45). For even the Son of Man did not come to be served, but to serve, and to give His life a ransom for many

B.   He is the Good Shepherd who gave his life for his sheep.

C.  The Sinless One assumed the burden of our sin and suffered in our place that we might obtain his perfect righteousness (2 Cor. 5:21). For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him.

III. Jesus Christ died on the cross to enlist and inspire our service.
A.  Because Christ died for our sins, we should be inspired to die to sin and to devote our lives to a life of righteousness, both in relationship to God and in our conduct toward our fellow humans (1 Peter 2:24).
     
B.   Next to our salvation, the privilege of Service is the greatest gift of God to humankind (Phil. 1:29) For to you it has been granted on behalf of Christ, not only to believe in Him, but also to suffer for His sake
(Rom.12:1-2). I beseech you therefore, brethren, by the mercies of God, that you present your bodies a living sacrifice, holy, acceptable to God, which is your reasonable service. 2 And do not be conformed to this world, but be transformed by the renewing of your mind, that you may prove what is that good and acceptable and perfect will of God.
Our greatest desire should be to live lives of holy worship and devotion to God. This requires separating ourselves from the pattern of the world. We are to offer our bodies as dead to sin, instruments of righteousness and as the temple of the Holy Spirit. (1 Corinthians 6:19-20) Or do you not know that your body is the temple of the Holy Spirit who is in you, whom you have from God, and you are not your own? 20 For you were bought at a price; therefore glorify God in your body and in your spirit, which are God's.
There is a real pressure to conform to the pattern of the present world system; this pressure must be firmly resisted by true believers. The reason is satan is the ruler of the world.          (1John 5:18-19) We know that whoever is born of God does not sin; but he who has been born of God keeps himself, and the wicked one does not touch him. 19 We know that we are of God, and the whole world lies under the sway of the wicked one.
Christians are exhorted in scripture to desist from all forms of worldliness, humanistic thinking, envy, hatred, revenge, impurity, lust, filthy language, immorality i.e. drugs, drunkenness, fornication and avoid bad company.
(1John 2:15-17) Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him. 16 For all that is in the world-the lust of the flesh, the lust of the eyes, and the pride of life-is not of the Father but is of the world. 17 And the world is passing away, and the lust of it; but he who does the will of God abides forever.
C.  Gratitude for God’s unspeakable gifts, through the Savior who was willing to die and who triumphantly lives again, should cause us to dedicate ourselves in Service to him.
Conclusion
As we partake of the bread, which symbolizes Christ’s body, and the wine, which symbolizes his blood, let us dedicate our lives and bodies to the Savior.
