"And having been set free from sin, you became slaves of righteousness." Romans 6:18
God has a plan for each and every one of our lives. After we are saved from sin, we should continue to seek God to find HI perfect plan for our respective lives. Once we find it, we should make it our plan.
"Therefore put to death your members which are on the earth: fornication, uncleanness, passion, evil desire, and covetousness, which is idolatry....But now you yourselves are to put off all these: anger, wrath, malice, blasphemy, filthy language out of your mouth. Do not lie to one another, since you have put off the old man with his deeds" Colossians 3:5,8-9
There is more to living holy than living a clean life (i.e. abstaining from and avoiding sin). That is a major part of holy living. However, in addition to that, we must obey Godís individual command for our respective lives. This involves consulting and obeying Him about our vocation, marriage, where to live, etc. This is what it means to have Jesus as our Lord.
"In all your ways acknowledge Him, And He shall direct your paths." Proverbs 3:6
Sin is a transgression of the command or will of God. When we fail to acknowledge God in all our ways, we sin.
"Come now, you who say, 'Today or tomorrow we will go to such and such a city, spend a year there, buy and sell, and make a profit'; whereas you do not know what will happen tomorrow. For what is your life? It is even a vapor that appears for a little time and then vanishes away. Instead you ought to say, 'If the Lord wills, we shall live and do this or that.' But now you boast in your arrogance. All such boasting is evil. Therefore, to him who knows to do good and does not do it, to him it is sin." James 4:13-17
We must obey Godís call on our lives in the area of ministry. God manifests His will to us by His anointing. The anointing is that special favor and unction (ability and knowing) given to man by God to do a certain thing. We should be very sensitive to that anointing or unction, because God uses it to teach us how He wants us to be a blessing to others. We should always obey Godís anointing. When we do we are yielding our members as servants of righteousness.
"But you have an anointing from the Holy One, and you know all things....Therefore let that abide in you which you heard from the beginning. If what you heard from the beginning abides in you, you also will abide in the Son and in the Father. And this is the promise that He has promised us--eternal life....But the anointing which you have received from Him abides in you, and you do not need that anyone teach you; but as the same anointing teaches you concerning all things, and is true, and is not a lie, and just as it has taught you, you will abide in Him. And now, little children, abide in Him, that when He appears, we may have confidence and not be ashamed before Him at His coming. If you know that He is righteous, you know that everyone who practices righteousness is born of Him." 1 John 2:20,24-25,27-29
"And do not present your members as instruments of unrighteousness to sin, but present yourselves to God as being alive from the dead, and your members as instruments of righteousness to God." Romans 6:13
