"There was a man in the land of Uz, whose name was Job; and that man was perfect and upright, and one that feared God, and eschewed evil." Job 1:1
If Job had physically died in the moment of that writing of that verse, he was already a perfect man according to what he had and according to what he knew and believed. He would perhaps have been as the 'so called' good thief on the cross was when he had his short conversation with Jesus before the soldier broke his legs. Both men were already overcomers... that is, both of them had already overcome the things of which they were aware standing between them and God. They were ready to meet their Maker more closely!
Can a person continue to grow closer to and more like God once he has truly repented before God? The example of Job indicates, yes. to me.
If we have truly repented, we are working in the Daylight as did Jesus. But... at that first repentance do we even know all of our own dark places? By opening up those remaining dark places to God when he knocks on our door, can He not, will He not, then enter into to each such place as it is opened and expand the place of Light in us by killing the beast that had the rule perhaps unbeknownst to us in that place?
Did Jesus, the man of flesh have beasts that needed to overcome/killed? If the beasts are temptations, then the answer is, yes!
Temptation is not sin. However, when a man succumbs to a temptation then he has started down the pathway away from God. he has sinned. Jesus never did that. He killed all of his own beasts before any of them could cause him to sin.
"For we have not an high priest which cannot be touched with the feeling of our infirmities; but was in all points tempted like as we are, yet without sin." Heb 4:15
"Wisdom hath builded her house, she hath hewn out her seven pillars:
She hath killed her beasts; she hath mingled her wine; she hath also furnished her table." Prov 9:1-2
Before Jesus went to the cross, he killed all of his beasts. He overcome all of the temptations in his own little world as a carnal man subject to temptations.
"These things I have spoken unto you, that in me ye might have peace. In the world ye shall have tribulation: but be of good cheer; I have overcome the world." John 16:33
Jesus had done if for his own man of carnal temptation, so that before he went to the cross he was no longer "in" that world of temptations.
And now I am no more in the world, but these are in the world, and I come to thee. Holy Father, keep through thine own name those whom thou hast given me, that they may be one, as we are." John 17:11
So then having overcome, Jesus then went to the cross making a Way for us to follow Him. Can we through the power of the Holy Spirit in us overcome the temptations before our allotted time as a man has ended?
