The list of things in verse 5 concerns problems of a sexual nature; those listed in verses 8-10 concern attitude and speech. When we become Christians, we make changes in our lives. The way that we think changes. Life is viewed in light of eternity, not just in terms of daily living. Those things that are most important now relate to Jesus and His church. We know that Jesus is coming back for His people (alive or dead) to take them to heaven. Jesus is our life (Col. 3:4). Until the time He returns (2 Thess. 1:7-9), we must devote ourselves to Him.
Our attitudes must be different from the sinful ones we once had. We must control anger rather than expressing it for all to see. We must watch what we say: a filthy mouth should not be found in a cleansed soul. Our tongues should not be used for corrupt speech or to deceive people. Certainly people devoted to Truth cannot tell lies. But Christianity is more than just putting off the old thoughts, attitudes, and actions. We must put on the new clothes that God wants us to wear.
Therefore, as the elect of God, holy and beloved, put on tender mercies, kindness, humbleness of mind, meekness, longsuffering; bearing with one another, if anyone has a complaint against another; even as Christ forgave you, so you must also do. But above all these things put on love, which is the bond of perfection. And let the peace of God rule in your hearts, to which also you were called in one body, and be thankful (Col. 3:12-15).
Changing oneself is not easy. Pride must be changed into humbleness of mind; anger must be changed into kindness, longsuffering, bearing with one another, and forgiveness. Selfishness must be changed into love. Becoming a Christian means becoming a new person--not only in relationship to God, but to other people, also. We are to conform ourselves to the image of Christ (Rom. 8:29). Even if we must suffer for righteousness' sake, we are to follow His example (1 Peter 2:21-24).
The new life also brings a freshness to all earthly relationships. It means we will be better husbands and wives (Col. 3:18-21; Eph. 5:22-33). We will be better servants (workers) and masters (Col. 3:22-4:1). We will be better citizens (1 Peter 2:13-17). How glorious it is to be a Christian, a new person with better earthly relationships! The greatest blessing of all is to be one of God's children walking in the light rather than one of Satan's walking in darkness.
Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new (2 Cor. 5:17).
Obligations
If you have been baptized into Christ for the forgiveness of your sins, you have many blessings and also many obligations or duties. The first one is to put God first in your life (Luke 14:26-33; Matt. 22:37-39). The second one is to "work out your own salvation with fear and trembling" (Phil. 2:12).
Then you must "love your neighbor as yourself" (Matt. 22:40). You have obligations to your brethren in the church as well as to those who are not Christians. All brethren are to "love one another," as Christ loved us (John 13:34-35; 1 John 4:7-8). There are a number of passages that speak of ways to help each other, such as of teaching, admonishing, encouraging, and serving one another (Eph. 5:19; Heb. 3:13; Gal. 5:13, and many others). What about those who are not Christians?
Walk in wisdom toward those who are outside, redeeming the time. Let your speech always be with grace, seasoned with salt, that you may know how you ought to answer each one (Col. 4:5-6).
Paul said that he was debtor to all men; he owed them the gospel (Rom. 1:14); so do you. If you have not yet obeyed the gospel, please consider carefully that your sins have earned you eternal damnation, but God wants you to have eternal life (Rom. 6:23). Contact someone in the churches of Christ and ask him to baptize you for the forgiveness of your sins (Acts 2:28). God will richly bless you.
