Hebrews 10:23-27

23 let us hold fast the confession of our hope unyieldingly. For he who promised is faithful.

24 Let us consider how to provoke one another to love and good works,  25 not forsaking our own assembling together, as the custom of some is, but exhorting one another; and so much the more, as you see the Day approaching.  26 For if we sin willfully after we have received the knowledge of the truth, there remains no more a sacrifice for sins,  27 but a certain fearful expectation of judgment, and a fierceness of fire which will devour the adversaries.
