They could for short periods of time.
But they couldn't "cast off the flesh", permanently, like NT believers can.
Wrath, strife, envy, all that a typical forum is, are not the fruits of the Spirit.
Galatians 5:19 Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness,
20 Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,
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.
Making peace, goodness ( to others) meekness, they are not what you can find in an environment of wrath, and strife. ( the typical many years non stop, daily forum discussions/disputes, contentions/debates.)
Galatians 5:22 But the fruit of the Spirit is love, joy, peace, longsuffering, gentleness, goodness, faith,
23 Meekness, temperance: against such there is no law.
