To Israel, Christ sent His 12 apostles to preach "the
gospel of the kingdom" with SIGNS of confirmation (Matthew 10:5-8)
Christ encouraged John the Baptist via SIGNS to trust
Him as the MESSIAH (Matthew 11:2-6)
Christ rebuked the Pharisees for attributing His SIGNS
to Satan (Matthew 12:24-28)
DURING "the dispensation of grace" (Ephesians 3:2),
the saints walk by faith and NOT by SIGHT (II Corinthians 5:7) and enjoy SPIRITUAL blessings in the HEAVENLY places (Ephesians 1:3)
The SIGN of resurrection is the SEAL of that authority
for both Christ and Antichrist (Revelation 1:18 cf.Revelation 17:8),
which is how Antichrist blasphemes the NAME of Jehovah (Exodus 3:14 cf.John 8:58)
The second beastcauses the worship of the first beast
The SIGN of "fire from heaven" was used by God
to acknowledge the sacrificial offerings (I Kings 18:36-39), which is how Antichrist blasphemes the TABERNACLE of Jehovah (Revelation 13:6)
when he poses as God in His TEMPLE (II Thessalonians 2:4)
The SIGN of giving life to an image (idol) which has no
life (Psalms 135:15-18) serves as a visual reminder to the resurrection of the one who it
represents, which emphasizes his blasphemy of the NAME of Jehovah (Revelation 13:6)
