I only say swt or may he be glorified and exalted in a paragraph or dua

If I already said it, for example, in a simple paragraph, yet powerful like this:

God, may he be glorified and exalted(s.w.t. or subhanahu wa ta'ala), please forgive my sins.
Help me reach your Jannatul Firdaus
O God, you are my Lord
There is no other God but you
To you I turn into repentance
I love you forever

Now, at the 3rd stanza, I didn't put (swt) again and I also say (swt) on the Lord at times before. Even on God, or that Lord. I say, "Lord(subhanahu wa ta'ala) because I've read in a book that God, not the word Allah, is the same with Allah. There's no difference. I already somehow know that. Islam guides us.

If in your heart, like dhikr, you feel Allah is already the glorified and exalted, to save energy, I think you can just pronounce it once at the beginning while on the go to pronounce Allah's name on the others.

That's on a paragraph you're reading. When making a separate dua, like for example, while reading that, you thought you want to dua for your mom working outside, you can pronounce (swt) again on that separate glorification. You can say it again as to respect the creator and never forget to glorify him and exalt him just like what many of us do. But in that paragraph, I think you can just pronounce it once.

I just wish to help. Alhamdulillah. Islam is within reason. The things that we cannot comprehend at times that we might have considered so unreasonable is also reasonable. It just needs time to be realized.
