To my brothers/sisters that have the spirit of Christ, it may be important to keep in mind some things:
1. Our brother (the Apostle Paul), when speaking to the Galatians, (prefaced condemning some to hell)...by saying "if man or angel" preach to you with another gospel, may he be "accursed"). He said this twice! (I think this is imporatant in that context here, because since we have Scriptural precedent for (prefacing before warning of being declared, condemned - told you may "go-to-hell"), means clearly, that if another one with the spirit of Christ also says the same...it does not mean, "God wouldn't say that"; or "God wouldn't act like that" or, "A Christian wouldn't act or say like that"...on the contrary.
2. The two witnesses, and I don't claim to know them, when they appear, it will only be for a relatively short time, about three and a half years. They have a specific job to do. I think it's fair to say, that (they will not exhibit all of the "personality" characteristics of God...especially those related to God's kindness, gentleness and patience. This can be derived (again from their brief ministry) and importantly, by the actions they perform, namely, like "devouring their enemies with fire" and "shutting up heaven", where drought and famine run rampant, and "turing the waters to blood", and importantly, being hated by, pretty much all other human beings (but for the few of us that will understand the truth), since these two witnesses will "torment them that dwelt on the earth".
Praise God forever and ever
