My post earlier already gave you several good reasons... so drink up
Here's two witnesses from the NT concerning what the Lord says...
1 Corinthians 6:9-11
Know ye not that the unrighteous shall not inherit the kingdom of God? Be not deceived: neither fornicators, nor idolaters, nor adulterers, nor effeminate, nor abusers of themselves with mankind,
Nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners, shall inherit the kingdom of God.
And such were some of you: but ye are washed, but ye are sanctified, but ye are justified in the name of the Lord Jesus, and by the Spirit of our God.
Galatians 5:16-24
This I say then, Walk in the Spirit, and ye shall not fulfill the lust of the flesh.
For the flesh lusts against the Spirit, and the Spirit against the flesh: and these are contrary the one to the other: so that ye cannot do the things that ye would.
But if ye be led of the Spirit, ye are not under the law.
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.
But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
Meekness, temperance: against such there is no law.
And they that are Christ's have crucified the flesh with the affections and lusts.
