This is so simple.
It’s nearly too simple for many of us. I suspect it’s much too black and white!
The Spirit arrives into our lives in a very ordered way – remember it’s the Spirit that brings us into intimacy with God.
There are ordered steps and each step builds on the previous step.
If you love me – that’s the first step; if you love ❤️ me… look how he’s phrased it; if…
If you love me, then the second step; you’ll keep my commandments. So the second step is keeping his commandments but you’ll never have one without the other.
Then Jesus repeats himself, making the same point but in a slightly different way.
And then to really push the point home he states that the reverse is true: “Those who do not love me do not keep my words.” Few of us are comfortable with this, typically we’d say; much too black and white!
So, the Spirit does not enter every life, only the lives of those who love Jesus (God), and keep his commandments, his Word.
So we’re given a reason for lack of intimacy with God.
Finally we’re told something of what the Spirit’s presence does; it causes us to remember Jesus teaching, his teaching becomes part of who we are, my identity, your identity, our identity.
