Faith and Duty

And the apostles said unto the Lord, Increase our faith. And the Lord said, If ye had faith as a grain of mustard seed, ye would say unto this sycamine tree, Be thou rooted up, and be thou planted in the sea; and it would obey you. But who is there of you, having a servant plowing or keeping sheep, that will say unto him, when he is come in from the field, Come straightway and sit down to meat; and will not rather say unto him, Make ready wherewith I may sup, and gird thyself, and serve me, till I have eaten and drunken; and afterward thou shalt eat and drink? Doth he thank the servant because he did the things that were commanded? Even so ye also, when ye shall have done all the things that are commanded you, say, We are unprofitable servants; we have done that which it was our duty to do.

Luke 17:5-10

Jesus told him, "I am the way, the truth, and the life. No one can come to the Father except through me." (John 14:6)
