What to do on Saturdays and Sundays?

From Monday to Friday, I would like to be concentrated in spending time to my job, that is:

• research. I need to publish papers. It seems that I am always in debt to the brazilian society.
• class. Teaching computer related things.

I understand that the Lord is honored when I execute my secular job, however, I would like to have a mind away from my job at weekends.

As I am preaching once a month, I would like to reserve Sunday to prepare the sermon. Until recently I was preparing the sermon on one day - generally the Sunday before the preaching. I was recording the sermon on a video. During the week before the sermon, I was watching myself in order to improve the sermon that was given "online" by internet. However, chatting with a friend of mine that is a quasi theology academic, I decided to improve the sermon. The fact is that my church is diminishing and it is very certain, that one cause is the lack of a proper message to our world. Preparing a message that calls attention in our "evil days" is very difficult, but it is not impossible. I decided to spend every three Sundays or more in preparing the sermon. The idea is to prepare a message specially to my church, publish it, in hope that is a message to the brazilian Nikkeis too.

 In Decalogue, the Israelite is commanded to keep the Sabbath. In most Christian churches, Sunday is the Dominus Day - the Lord's day. Today is Saturday and I would like to make a good use of it. 

How?

One idea is to use Saturday thinking about some way to earn money, besides my job. However, in this case, Saturday doesn't look the Sabbath. As I am not an Adventist or jew, it seems reasonable to me. I am saved by Jesus and not by keeping Jewish rules. I certainly respect the idea of resting one day per week as much as not eating raw meat, but both of them are not a commandment to me (because I am not jew).

Another idea is to visit my old father with his problems. 

In September, 5th, 2020, Saturday, I was going to visit my father when I had a bike accident. I broke one arm and lost part of my tooth. At that moment, he didn't recognize my pains just to visit him. He was reluctant to let my brother use his car to take me to the emergency room. 

He doesn't usually become glad when I visit him. In fact, today, talking by internet (by my brother's smartphone), he told that it is not necessary that I visit him. Unfortunately, dad is not thinking clearly. He is locking himself in a prison due to his paranoia.  I would rather much more staying at home, but I must visit him, anyway, despite what he wishes.
