Has anyone witnessed these signs in Mark 16:17-18 today? How would you challenge those supernatural claims?
All beleivers have witnesed the effect of that parable. But not the ones that went out from us, not of us.
Signs are for those who reject prophecy. All believers follow after those signs as to their “spiritual meaning” of that parable. the poison of false prophecy has not effect on them
Serpents typify false prophets that walk after the oral traditions of men and in doing so make the faith of God without effect. In that way Christ called the father as a law of men... a brood of vipers. Poison represents false doctrine .Believers will not be deceived by them… they are given the faith to understand that God is no longer brining any new prophecy .The book of prophecy the bible is completed (perfect) it is sealed up in that way till the end of time.
Those who would ignore the warning have drank of the poison of asps .. that sign in Mark 16:17-18 speaks to the rebels.
Signs follow after believers...they do not point to them as eveidence they have the Holy Spirit... believers are not to seek signs or test God to serve as a sign
to unbelievers.
That sign or parable is like the sign of the pole and the brazen serpent .Brass speaks of judgment in that way .Those who did not beleive prophecy died from the poison (false prophecy)
