I am not posing myself as an expert, or as a teacher in this discipline, only a practitioner, but to answer your question:
The one thing that comes to mind as I read your question is the motivation I had (have) to need this time with my Father. That’s how I started. I remember explaining it to one person, years ago, to be similar to going over to my earthly father’s house and sitting on the front porch swing for a few hours. Either we talk, or we simply sip our tea in silence, either way the effect was the same. The communication was love.
The need was already present within me. There was an initial difficulty in adjusting my burgeoning schedule to accommodate this new rhythm, but my need for the time of relationship building only increased as I practiced it. It was initially similar to how God The Father allotted a day of rest for his chosen people; a day to trust Him that their prosperity was not dependent on their industry, but on their relationship to Him. I think He still invites us to test that promise, to dare to step out onto His provision; to trust while we put our full weight on the rock. This is how we prove to our naturally-skeptical minds that the rock does not move under our weight; the sea will part, our schedule will give way to our purpose.
You said:
The telling word in your question was “unavoidable”. We are affective humans, and we naturally prioritize the tasks and events to which we give ourselves according to how “unavoidable” they are; trying to get the most imperative ones done without too much neglect of the less important. If spending time with The Lord is less important than other competing tasks, then trying to shoe-horn it into a too-full schedule will feel more like a burden than a time of rest; contrary to what your Father designed for your life. I was never comfortable making time with my father one-more-thing-to-do. I fully understand how the world imposes its will and makes demands for our time, sometimes unreasonable demands, but imperatives we feel we cannot ignore. The often-overlooked secret weapon we have in our arsenal, against which the world has no defense, is prayer. We can ask our Father to help us – to part the sea, to vanquish the enemy, to show us how we can together appropriate our time making our relationship our primary priority. Sometimes we don’t have, simply because we don’t ask.
I also see this time as a privilege, and so I understand when some outside imperative impinges on my privilege. Maybe someone plans a wedding, or a funeral, or a family event, or work insists on my presence, or any other imposition that assumes I’m available on Sunday. It happens, and I don’t sweat it, and my Father doesn’t sweat it either. We are both disappointed, but we get over it. Jesus taught some lawyers and Pharisees this principle by saying to them “Which of you, having a donkey or an ox that has fallen into a pit, will not immediately pull him out on the Sabbath day?” Luke 14:3-5 While I’m not talking about the law, the principle gained here is that God is not trying to make your life more difficult or burdensome, but the opposite. Even so, sometimes stuff happens, and God does not prevent it, but has, even in these intrusions, His mysterious way to build our faith and dependence on Him. In incidents as these the adage holds true, “absence makes the heart grow fonder”.
