Matthew 10:28,32,33
And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell.

Therefore, whoever confesses Me before me, him I will also confess before My Father who is in heaven.
But whoever denies Me before men, him I will also deny before My Father who is in heaven


believe and fear of the Lord can never be separated
if there's no fear, there's no authentic faith

James 2:19
You believe that there is one God. You do well. Even the demons believe—and tremble!
