With the 'passing away' ( I Corinthians 7:31, 3:7 ( Hebrews 8:13 ) I John 2:8 & 17 ) of the Old Covenant ( Mosaic ) and the transition, or re-birthing of the Church, as the Body of Christ, the true 'Israel of God', the signs which pointed to that greater spiritual reality in Christ ceased to be necessary. When one has reached the destination, the reality to which all signs have pointed; signs are no longer necessary, and can even be detrimental!
That I will pour out My Spirit on all flesh;
Your sons and your daughters shall prophesy,
Your old men shall dream dreams,
Your young men shall see visions.
And also on [ My } menservants and on [ My } maidservants
I will pour out My Spirit in those days.
