Ok, I read through your piece, and I assume you are referring to this right here:

Comparing the two covenants:
Jewish: When the Jewish people sinned, God's instructions in Leviticus were to present sacrifices to the Lord to atone for their sins. In other words, although sin separated them from God, in this case the Jewish people that sinned did not stop being God's chosen people. They remained God's chosen people as long as the daily sacrifices were presented as instructed (Exodus 19:5).
Christians: When the Christian believers sin, Jesus provided the perfect prayer for the forgiveness of their sins (Matthew 6:9-13 and Luke11:2-4). As long as this prayer is recited daily as instructed by Jesus, a Christian remains in Jesus, and Jesus remains in him. And those Christians remain belonging to Jesus (saved):
John 15:4:
Remain in me, as I also remain in you. No branch can bear fruit by itself; it must remain in the vine. Neither can you bear fruit unless you remain in me.
But if a person keeps on sinning for a long time without praying the Lord's Prayer and without growing spiritually, eventually God gives up on him. This person would be one of these cases:
Matthew 13:22:
The seed falling among the thorns refers to someone who hears the word, but the worries of this life and the deceitfulness of wealth choke the word, making it unfruitful.
John 15:6:
Jesus said in the Vine and branches parable: If anyone does not remain in Me, he is like a branch that is thrown away and withers. Such branches are gathered up, thrown into the fire, and burned.
Luke 13:6-9:
Then he told this parable: "A man had a fig tree, planted in his vineyard, and he went to look for fruit on it, but did not find any. So he said to the man who took care of the vineyard, `For three years now I've been coming to look for fruit on this fig tree and haven't found any. Cut it down! Why should it use up the soil?' "`Sir,' the man replied, `leave it alone for one more year, and I'll dig around it and fertilize it. If it bears fruit next year, fine! If not, then cut it down.
Note: What is "fruit"? It is spiritual maturity. God is patient with us. He won't strike us down if we skip a few times praying the Lord's Prayer, or if we don't read our Bible for spiritual maturity, as in the fig tree parable, "Fertilize and wait another year..."

Again I would have to respond that you are presenting dangerous teaching here. You are resting "abiding in Him" completely under the domain of saying the Lord's Prayer. It's downright cultish I'm afraid. It makes the assumption that the handwriting in the ordinances that were against us have not been nailed to the cross, and are therefore still in force, i.e. that we are not dead to sin and alive unto Christ now, so our sins must be continually addressed like the Jews had to make sacrifices.
You seem courteous and pleasant enough, but I don't like this teaching. I think it creates a potential form of self-condemnation, and leads others to eventually start asking themselves just how often they need to say their Lord's Prayer or God may abandon them. It's spooky theology, and unnecessary IMO.
