Now the works of the flesh are manifest, which are these: Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies, 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. (Galatians 5:19-21)
We wrestle every day against the sinful influences of this world. They bombard us everyday in every way. Our sinful flesh or self nature does not have the capacity in and of itself to combat these influences thus our spirit has to fight against the works of the flesh. The works of the flesh are sinful qualities which contrast the fruit of the Holy Spirit.
For all that is in the world, the lust of the flesh, and the lust of the eyes, and the pride of life, is not of the Father, but is of the world. 1 John 2:16
Murder is not the same as self-defense or an accidental killing. Murder is not the same as imposing the death penalty on a person who has killed someone. This was a judgment established by God in Numbers 35. One of the first commandments given by God was "Thou shalt not kill".
The Bible warns that the drunkard will be poor:
For the drunkard and the glutton shall come to poverty: and drowsiness shall clothe a man with rags. (Proverbs 23:21)
If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. (I John 1:9)
