You are yet tilting against windmills or kicking on open doors. Me and others here have not denied that fruit bearing of saved souls will bring about a willingness to follow Jesus, including what you have mentioned above. But the term requirement that you used is totally off base. You are saying that there is a requirement to be fulfilled by us, for salvation, when all requirements for same was fulfilled in the person and work of Jesus Christ. The reasoning you are approaching amounts to that the work and person of Jesus Christ is not enough to actually save anyone, cos there is a requirement to be fulfilled in us so that one can be saved. You are then confusing fruit with condition/requirement! This might, worst off, stem from ignorance about the righteousness of God, as revealed in the gospel. Through someone else, or yourself, you have been tossed and carried about by some wind of erroneous doctrine?
This all sounds good, until you start to distinguish between a believer and a non-believer.
There is something in the believers response to God, which differentiates them from the non-believer.
If this was not so, all people are saved.
If you say it is just Gods choice, there is no difference, then you are into fatalism, where God is supreme
and nothing the believer does determines their destiny.
Paul is very different. He is very anxious that the believers walk in the way of Christ, hold to faith to the
end, and show his work has not been in vain. This whole expression dictates the response of the believer
matters, not that it determines the free gift that has been offered but that the response is worthy of
God. Jesus is very concerned that though people understand and fall in love with the principles of the
Kingdom, they get lazy and start abusing one another. His warning is this is the same as becoming an
unbeliever and will be so judged.
The mystics here say things like once you are a child of God you cannot unbecome a child of God.
Jesus, Paul, Peter, John imply we should never take for granted our position before the King, and He
knows all, and we are continue in His ways, because His nature is always to reject and throw out the
unbelieving sinners who dishonour His word and ways.
With a teenager, and their teenage rebellion you get the idea of showing independence while staying
true to your relationships is hard with many ups and downs. But some do break with their family and
disown them, never to return. So I can see the argument from both sides, but it is always dependent
on the love and relationship which is still alive.
