Wrong. He said “And these signs SHALL follow THEM THAT BELIEVE.” It plainly states that ALL signs are for ALL who believe. Not a select few. THEM THAT BELIEVE. C’mon, read the words as they are. Not as you want them to be.
The signs shall follow them, not that all believers will perform them.
Mark 16: 19So then the Lord Jesus, after he spoke to them, was taken up into heaven and took his seat at the right hand of God.k 20But they went forth and preached everywhere, while the Lord worked with them and confirmed the word through accompanying signs.]l [And they reported all the instructions briefly to Peters companions. Afterwards Jesus himself, through them, sent forth from east to west the sacred and imperishable proclamation of eternal salvation. Amen.]
Who did Jesus work through? The Eleven. Not all believers.
