On the last and greatest day of the festival [Sukkot], Jesus stood and said in a loud voice, “Let anyone who is thirsty come to me and drink. Whoever believes in me, as Scripture has said, rivers of living water will flow from within them.” (John 7:37-38)
Multiple good articles have been posted on Scriptural evidence pointing to the rapture of the Church overcomers occurring on this last (eighth) day of the last of God’s three fall appointments with His people: the Feast of Tabernacles, or Sukkot. This is the one I strongly recommend reading now, for today is the great last day of the last of the three fall appointed times. Maranatha!
