"All" means "all". You need to sell your computer, your phone, and your bicycle.
This word of Jesus is His way of setting forth an impossible requirement so that we will come into the kingdom through the proper channels: through faith in Him, rather than by trusting in our works.
You are not being faithful to the text. Better explain this again, a little bit clearer. I am not going to read your Bible Study. So bring your teaching to the forefront.
Good works are not mandatory for salvation. See Romans 4:6, Romans 11:5-6, Titus 3:5, Ephesians 2:8-9.
They will normally result out of a true salvation; but that is a different thing.
Okay, if we do not bear good fruit we will be cut off from the vine and cast into the fire; however your teaching misses out on something very important: the way that we bear fruit does not have to do with an effort to bear good fruit. We bear fruit because we are connected to the vine and drawing up nourishment from the vine. We have a relationship with Jesus Christ; we are connected to Him: the Spirit dwells within us, and therefore the Spirit, like the sap or blood of the plant, flows to the end of us as branches and fruit develops as the result. But our fruit does not develop as a result of the letter of the law. Because we have a relationship with Jesus we are obedient to the spirit of the law, Romans 7:6. But the letter kills and the spirit gives life, 2 Corinthians 3:6.
So then, if we do not bear good fruit, it is the sure sign that we are not abiding in the vine. But those who see the fruit in others and try to copy it are only going to produce plastic fruit.
Again I say, bearing the right kind of fruit is the result of abiding in the vine. We do this by staying in the word of the Lord and praying; we draw up nourishment from the vine in the doing of this. It is also called spiritual breathing. When we breathe spiritually, we will be alive; and the works that God has before prepared for us to do will be walked in. However this is not dictated by other people, but by the Holy Spirit who dwells within every believer.
The whole point of the original poster seems to be that a man is condemned if he does not do the works that he himself has placed it on himself to do. He is trying to impose on other people as required a behaviour that is not required by the scripture for salvation. It should be clear from scripture the following principle:
Rom 14:4, Who art thou that judgest another man's servant? to his own master he standeth or falleth. Yea, he shall be holden up: for God is able to make him stand.
The Bible tells us to "Be strong in the grace that is in Christ Jesus." (2 Timothy 2:2)
This teaching is not about grace but is a legalistic imposition that, if believed, will deter a great number of people from coming into the faith of Jesus Christ.
