Hebrews 6:9-12

Even though we speak like this, dear friends, we are convinced of better things in your case—the things that have to do with salvation. 10 God is not unjust; he will not forget your work and the love you have shown him as you have helped his people and continue to help them. 11 We want each of you to show this same diligence to the very end, so that what you hope for may be fully realized. 12 We do not want you to become lazy, but to imitate those who through faith and patience inherit what has been promised.
