"There is no 2nd class according to scripture. Ephesians 4:4 mentions only 1 hope."
Yes, and there is no such thing as a Christian who is not born of and indwelt by the Holy Spirit. Jn.3:3; Ro.8:9 Neither is there any Christian who cannot call God his Father or who is not justified by the blood of Christ. I Jn.5:1; Acts 13:39
144,000 is symbolic for the innumerable church of God. John hears the perfect number, Isreal squared and multiplied by 1000 meaning many and then turns to see the actual group in a heavenly setting of victory and celebration. This hearing and then seeing sequence is commonly used by John when displaying his symbols in Revelation. Eg. He hears the lion and turns and sees the Lamb.
It is never wise to base essential doctrine on Revelation or apocalyptic literature.
