James 2:26: For as the body apart from the spirit is dead, so also faith apart from works id dead. ESV
Some interesting thoughts on this passage by A.W. Tozer:
Whoever said you could be a Christian without being a disciple? You cannot be a Christian without being a disciple. The idea that I can come to the Lord by grace, and have all my sins forgiving, and have my name written in heaven, have the carpenter go to work on a mansion in my Father’s house and at the same time I can raise hell on my way to heaven. I say it is impossible. It is unscriptural, it is not found in the Bible at all. You are not saved by your good works, no never are we saved by our good works, but we are not saved apart from good works. We are saved by faith in Jesus Christ alone, but out of that, springs immediately goodness and righteousness.
Flowers do bring spring, but you cannot have spring without flowers. It is not the birds that bring the summer, but you have no summer without birds. It is not righteousness that saves me but salvation brings righteousness. The man who is not ready to live right, he is not saved; he will not be saved, and he will be deceived in the great day.
