1. III. Truth Will Not Associate With Deception (7-11)
    1. A. The Deception Regarding Christ's Manhood (7-8)

Paraphrase

7 Those who deny that Jesus was truly here - a man of flesh even as we - are doing nothing other than trying to lead us astray. 8 Against such deceptions we must be vigilant, that we not lose the ground of faith that we've gained, but rather continue strong to the reward God has for us.

Key Verse

8 - We must be careful to stand firm. Only those who persevere attain to the reward.

Thematic Relevance:

Deception is the opposing of the truth we have come to know. The case in point here involves His humanity. Some denied the truth of His birth, some the truth of His death, some that He was ever truly here at all. But in all cases, His humanity was the truth - the essence, the reality matching the appearance. Furthermore, He was more truly human than any before or after, fulfilling what humanity was supposed to be.

Doctrinal Relevance:

Jesus came in the flesh, was born and died as men are born and die.

Moral Relevance:

It is our duty to withstand the temptations of deception. Many will sound good. Many will sound perhaps more reasonable than the truth. It is only by solid grounding in the whole truth - which can only come of having the Holy Spirit abiding in us to relay that truth - that we can stand against such deceptions and achieve the goal of steadfastness.

Questions Raised:

What is the full reward? Does v8 imply that the elect can fall?

New Thoughts

The full reward: the perfect and complete wages due to us for our service, or the abundant fruit resulting from our toils and endeavors. Either way, this precludes being blessed for sitting on one's duff. Note the parallel of 1Co 3:8 - each rewarded according to his work. It's not works salvation, it's working because of salvation. Our ticket to heaven does not hinge upon our doing things, but the quality of that heavenly life would seem to. God's pretty clear on the fact that He has little use for the sluggard. He is not a rewarder of loafing. This also comes back to the point of the previous section, which is that love obeys. God has commanded us to do good works, He has declared that we were created for that express purpose (along with giving Him glory and worship.) It's His point in having us about. To not labor would be to ignore our instructions, which would be to despise the instructor. It's a side point to this particular passage, and yet so clear. We need to keep this in mind, as we're told not to be 'busy.' There's truth to that, but there's danger as well. We ought indeed to be very busy, but only about the work God has appointed to us. To often, we're very busy with things that have the appearance of good works, but which were not our job. We're in effect avoiding what we were told to do. We're like the child that doesn't want to do chores, and does artwork instead, hoping the pretty picture will satisfy their parent in spite of their disobeying the command to do chores. We're still little children in so many ways. God have patience with us, and teach us to recognize ourselves in our children that we might have patience with them, too.
