One reason why you should have your quiet time.

Not doing your quiet time is
likened to wearing a weak helmet of Salvation. Your head, the most important part of your body is less protected. If the devil attacks your head and wins he has total access to u. He attacks your mind interface (sounding geeky 😏) and that's his point of entry.

The helmet we wear as Christians is the helmet of Salvation. Salvation is being delivered from sin and it's consequences and taking and making Christ your Lord and Personal Saviour. And quiet time is a demonstration of your Personal relationship with God. If u don't have your quiet time, there's a weakened relationship between you and God. And so a weakened relationship with your Personal Savior, resulting in a weak helmet of Salvation and then the devil easily hacks into your head and does stuff. Protect your head. Do your quiet time.
