Don't get me wrong, we all need to look presentable when we go to church, but the use of a suit and tie in 100 degree temps, is a bit much. I am not condemning anyone who does this, but man, you must suffer on those hot days.
Now, when the bible was written, didn't they all wear robes, even to church. I do not think that pants or trousers were available back then, yet alone, a tie.
The main thing is that we are dressed up in the "heart", the "inner man" so to speak. I am dressed up wherever I go. I have a long white robe on, have new shoes on my feet. I am dressed and ready to go when He calls my name. Of course, the dress code for our heavenly address is mandatory.
