God is good and He is the greatest being in existence. He is unfathomable and incomprehensible.
God does great things that deserve thanks and praise and adoration.
As Christians we should expect great things out of our powerful and perfect Father. Miracles and healing are typical for our Lord. Those things are in His nature. It is a part of Him to do things that seem impossible to us. So since we expect those things, maybe they shouldn't seem impressive.
At the same time "impressive" is like "impression" and so as I learn more about my Father I find things about the same unchanging God that are simply new to me. Those things should be impressive. Also, although we expect things from Him, they are always unexpected. The way that He answers prayers is never something I can figure out. Sometimes He waits months or years, but sometimes He answers prayers instantly. And no matter when or how He answers those prayers always puts me on my knees. No matter how much I expect the answer and believe that there will be an answer, when the answer comes I fall even deeper in love with Jesus because He blows my mind every time.
- to affect deeply or strongly in mind of feelings; influence in opinion.
- to apply with pressure, so as to leave a mark.
- to urge, as something to be remembered or done.
- to fix deeply or firmly on the mind or memory, as ideas or facts
God is all of those things. Everything He does leaves a mark on His followers. Everything He is affects me deeply. Every time He shows himself He is fixed on my mind. There is nothing about my God that is not impressive.
Although we should believe and be expectant followers understanding that our God can do all that He wants, He is impressive because He cannot appear without changing the hearts and lives of those who see Him.
