Galatians 5:19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
These are four external acts of sin. Adultery is usually done in secret, fornication, uncleanness and lasciviousness are often associated with being drunk or operating in the dark.
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
These are more hidden and inward acts of sin. People often pursue idolatry and witchcraft as a way to get an advantage over others. Hatred is often hidden, many times those that hate you will try to hide that fact for an advantage. Variance refers to contentions, like a quarrelsome wife. We generally do not think of this as being as serious as the previous seven, but this is clearly a symptom of the corrupt flesh. Emulations are when you get very upset due to envy, indignation or jealousy. For example in Luke when they were going to cast Jesus off the edge of a cliff it says they were filled with wrath. Strife refers to a political competition, turning the church into sects and trying to get votes for yourself. Seditions takes that one step further, where you want to cause a schism in the body of Christ. Heresies are schools of thought like Pharisees and Sadducees.
21 Envyings, murders, drunkenness, revellings, and such like: of the which I tell you before, as I have also told you in time past, that they which do such things shall not inherit the kingdom of God.
Envying is when you do things prompted by envy. How many murders are prompted by envy, or hatred or idolatry? Covetousness is often equated to idolatry. How many murders are just an extreme form of wrath, strife or sedition? You reap what you sow. Someone who is lascivious can easily go from there to uncleanness to fornication to adultery. It is difficult for someone who never committed fornication to then commit adultery. Likewise all these other things: Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, and envyings can all culminate in murders. This word for drunkenness is first used to refer to being overcharged with the cares of this life and the things of the world. When you are intoxicated you are less able to control yourself, so anything in the world that would cause you to be intoxicated. Could be alcohol or drugs or anything else that can be a sinful addiction. Revellings is similar to what happens when a team wins the Superbowl and all their fans go out and celebrate and get drunk.
22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith, 23 Meekness, temperance: against such there is no law.
These nine things are like the antidote to the works of the flesh. Either you are filled with love or you will be filled with hate. You can be filled with joy or you can be filled with envy. You can be filled with peace or with wrath. You can be filled with longsuffering or you can retaliate. Women often commit adultery in retaliation, murder can also be a form of retaliation. You can be filled with gentleness or with anger. You can be filled with goodness or uncleanness. Filled with temperance of drunkenness. Filled with meekness or strife.
24 And they that are Christ's have crucified the flesh with the affections and lusts.
This is the problem with "Once Saved Always Saved", doctrine and their condemnation of "works salvation". It is not Jesus, it is you that must crucify the flesh with the affections and lusts. We all have the flesh. It brings shame to us, when we get saved the light shines and we are ashamed of our flesh. At that time we must actively "crucify the flesh". You may stop going out to the bar, stop hanging out with certain friends, and stop putting yourself into a position to be tempted. Yes, Jesus forgave you and purchased you with His blood. But now, you respond by crucifying the flesh with the affections and lusts.
25 If we live in the Spirit, let us also walk in the Spirit.
If we claim that we are saved, children of God who are going to heaven, then lets live a life that expresses that. This does not mean we have a religion with a whole bunch of rules, instead we have one rule. Walk by the Spirit. Let the Spirit talk to you, if the Spirit does not want you to do something you will lose the life and peace, so take heed to that.
26 Let us not be desirous of vain glory, provoking one another, envying one another.
To be desirous of vain glory is covetousness, that is idolatry. Out of that you get witchcraft. Provoking one another is retaliation, it can be in the form of adultery, or murder or contentions. Envying one another is worse, it indicates you are obsessed, filled with hatred, jealousy, strife. But these three things are the early warning sign to you. You have a list of things that if you do those things you won't inherit the kingdom of God. But before you would even go that far you will have this desire for vain glory, and from that you may provoke others or envy others. That is your warning that you are in the flesh, crucify that.
