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. We want each of you to show this same diligence to the very end, in order to make your hope sure. We do not want you to become lazy, but to imitate those who through faith and patience inherit what has been promised.So there are two things I get from here. First, that "helping his people" is very important to God. Sure, feeding the poor and healing the sick and giving the good news to the lost -- those are important. But so are acts of service to the church.Hebrews 6.10-12
Second: workaholism bad, laziness bad, diligence good.
