Good morning Epi,
It's for all of us. And the apostle John wasn't talking to gnostics.
1John 2:12 I am writing to you, little children, because your sins are forgiven for his name's sake.
1John 2:13 I am writing to you, fathers, because you know him who is from the beginning. I am writing to you, young men, because you have overcome the evil one. I write to you, children, because you know the Father.
1John 2:14 I write to you, fathers, because you know him who is from the beginning. I write to you, young men, because you are strong, and the word of God abides in you, and you have overcome the evil one.
Let's use some more Scripture.
I think so too.
I don't believe in the what you have called - the higher walk, I think the right (and Biblical) phrase is - abide in Him -
1Joh 3:1 See what kind of love the Father has given to us, that we should be called children of God; and so we are. The reason why the world does not know us is that it did not know him.
1Joh 3:2 Beloved, we are God's children now, and what we will be has not yet appeared; but we know that when he appears we shall be like him, because we shall see him as he is.
1Joh 3:3 And everyone who thus hopes in him
purifies himself as he is pure.
1Joh 3:4 Everyone who makes a practice of sinning also practices lawlessness; sin is lawlessness.
1Joh 3:5
You know that he appeared in order to take away sins, and in him there is no sin.
1Joh 3:6
No one who abides in him keeps on sinning; no one who keeps on sinning has either seen him or known him.
1Joh 3:7 Little children, let no one deceive you. Whoever practices righteousness is righteous, as he is righteous.
1Joh 3:8
Whoever makes a practice of sinning is of the devil, for the devil has been sinning from the beginning. The reason the Son of God appeared was to destroy the works of the devil.
1Joh 3:9
No one born of God makes a practice of sinning, for God's seed abides in him, and he cannot keep on sinning because he has been born of God.
1Joh 3:10 By this it is evident who are the children of God, and who are the children of the devil: whoever does not practice righteousness is not of God,
nor is the one who does not love his brother.
Abide in Him, pray without ceasing[1 Thessalonians 5:17 and Ephesians 6:18], capture every thought [2 Cor 10:3-6] is how we protect ourselves from sin and when do sin after all it is not willingly [3:9] and we don't fall from grace as you believe, however when it is willingly (I can not imagine that) then I will agree with you, that is falling from grace and needs repentance.
Speaking for myself, not just a sample of grace, it was life changing, second blessing (the terminology of the holiness movement) was indeed about complete surrender and complete obedience.
You win, I surrender.
