According to the Apostle Paul, all believers are saints. There is nothing in the Bible that indicates that we should worship or pray to holy people who have died. Worship is to be directed only to the Father, Jesus and the Holy Spirit.
Revelation 15 pictures the “Close of Probation” when everyone on earth will have decided for or against the Gospel. The Faithful on the Sea of Glass Worship God while 7 Angels come out of the Temple to pour out the Wrath of God on those who have rejected the Gospel and are Persecuting the Faithful.
