Holiness and firstfruits

"Israel was holiness to the LORD, the firstfruits of His increase..." Jeremiah 2.3

Israel had double honour before God: it was the firstfruits and holy. Those who are born of the Spirit of God have the same characteristics: they are the first fruits and the sole property of the Almighty. Therefore, the Holy Spirit guarantees that everyone who is born of God overcomes the world (1 John 5.4).
