56:1,2 The Lord tells us what are his expectations of duty from us. Be honest and just in all dealings. Also strictly observe the sabbath day. To have the blessing of God upon employments all the week, make conscience of keeping the sabbath holy. Have nothing to do with sin. Blessed is the man that keeps his hand from all things displeasing to God and hurtful to his own soul. Those who, through the Spirit, wait for the hope of righteousness by faith, will be found walking in ways of holy obedience.
