Labor in the church

1. Alma 30: 34
     34 And now, if we do not receive anything for our labors in the church, what doth it profit us to labor in the church save it were to declare the truth, that we may have rejoicings in the joy of our brethren?
2. D&C 75: 28
     28 And again, verily I say unto you, that every man who is obliged to provide for his own family, let him provide, and he shall in nowise lose his crown; and let him labor in the church.
