Luk 17:7 “Will any one of you who has a servant plowing or keeping sheep say to him when he has come in from the field, ‘Come at once and recline at table’?
Luk 17:8 Will he not rather say to him, ‘Prepare supper for me, and dress properly, and serve me while I eat and drink, and afterward you will eat and drink’?
Luk 17:9 Does he thank the servant because he did what was commanded?
Luk 17:10 So you also, when you have done all that you were commanded, say, ‘We are unworthy servants; we have only done what was our duty.’”
Even though nothing we Christians are commanded to do will make us worthy of heaven, we still must obey God's commands (Mt 7:21-23); such is our duty (Ecc 12:13). So if we will always be unworthy of heaven because of our sins (Rom 6:23), how do we ever get there? God's grace (Eph 2:8) through an obedient faith in his Son (Rom 1:5; Ac 6:7; Heb 11:8)..
