Job 19:26
26 And though after my skin worms destroy this body, yet in my flesh shall I see God:
1 John 3:8
8 He that committeth sin is of the devil; for the devil sinneth from the beginning. For this purpose the Son of God was manifested, that he might destroy the works of the devil.
.
Before verse 26 I notice at Job 19:25 speaking about the ' latter day '
Resurrection Day (Jesus' thousand-year day) is the latter day or coming future day - Acts of the Apostles 24:15
It's that wonderful 'last day' as Jesus mentioned at John 6:40; John 6:44.
When Job will have a happy-and-healthy physical fleshly resurrection - John 5:28-29.
So, while alive still Job did Not literally see God ( John 1:18; 1 John 4:12; Exodus 33:20 ) but Job saw the 'manifestation of God's divine power' and why Job repented - Job 42:1-6
Through Jesus mankind will see the manifestation of divine power via the resurrection - Revelation 1:18
Satan manifested himself to be Satan the Devil from his first sin, so he became a devil from the start of his first sin.
'From the beginning' meaning once Satan chose to sin at that point was the start or the beginning of his sinning.
- James 1:13-15; John 8:44 Satan's first lie gave birth to sin.
Jesus was first manifested by giving himself as a ransom for us - Matthew 20:28
The final break up of sin will be manifested when Jesus destroys Satan - Hebrews 2:14 B
Manifested by destroying 'enemy death' - 1 Corinthians 15:26
