Honor the Lord with your wealth, with the first fruits of all your crops; then your barns will be filled to overflowing, and your vats will brim with new wine - Proverbs 3:9-10
The Literal Meaning: First fruits refer to the first portion of the harvest that is given to God. Most notably the first fruits are:
The first to come in time
A pledge or hope of the greater harvest to follow
Specially dedicated to God
The Spiritual Meaning: By giving God the first fruits, Israel acknowledged that all good things come from God and that everything belongs to God. Giving the first fruits was also a way of expressing trust in God’s provision; just as he provided the first fruits, so He would provide the rest of the crops that were needed.
Note that the Feast of First Fruits was instituted when the nation of Israel was still wandering, without land or crops. It was observed in faith that God would lead the people to the land he had promised.
The Prophetic Meaning: In Romans 8:23 Paul says that as a redeemed people we possess the first fruits of the Spirit. He is saying that the measure we have of the Holy Spirit is but a foretaste of the greater measure there will be in the time to come and that the gift of the Spirit is now a foretaste of the many other blessings we will have in due course.
While there is no New Testament admonition binding Christians to give first fruits we do know that God loves a cheerful giver. Christians are expected to give of our substance to support the work of the ministry. We, like the Israelites need to give our first fruit offerings. When we do, the Lord promises that there will be an abundance of blessings from the Lord! Our barns (financial accounts) will be filled to overflowing and our vats (lives) will be filled with new wine!
