This you know, my beloved brethren. Therefore putting aside all filthiness and all that remains of wickedness, in humility receive the word implanted, which is able to save your souls. But prove yourselves doers of the word, and not merely hearers who delude themselves. But one who looks intently at the perfect law, the law of liberty, and abides by it, not having become a forgetful hearer but an effectual doer, this man shall be blessed in what he does. They are not only very beautiful, but they are a promise of the harvest to come.
Christians are a kind of first fruits.
Verse 18 of our Scripture tells us that God brought us forth by His Word to be first fruits among His creatures. We are the first fruits because the harvest has only begun. Every growing Christian is a first fruit of this great harvest. So we have the idea of dedication also in the term first fruits. The rest of our passage speaks about hearing, receiving, and doing the Word of God.
