Any idea

KyRED,
Has this correct.Paul is using these men to illustrate what not to do.He is defining the path or realm of the obediance of faith.....the guardrails....
These men are offered as an example of what not to do in any case! They have gone outside the once for all time delivered faith.
To make shipwreck here is either heading in the direction of apostasy, or at best the sin unto death. Extremes are to be avoided and apostolic instruction is to be strictly adhered to.

Theological novelties are to be avoided.

Real christians look to serve the Lord,and do kingdom work,full of kingdom living. These men were going outside that set forth by apostolic teaching.

Osas is a watered down version of the biblical teaching that true saints will perservere in holiness and good works which are ordained for us....God working in us to will and to do of His good pleasure.
Because God has predestined us to be conformed to the Image of his Son.....sanctification has to go on bearing fruit unto holiness of life.
Any teaching that says otherwise is not of God. If there is not a pattern of fruit of the Spirit that is somewhat evident...that person needs to examine themselves ..if they are in the faith.

Most of the epistles lay out clearly what are conduct is to look like...eph 4-5 phil 2,3,4, titus 1,2,1 pet 3,4, col2,3....anything less is not God's salvation
