The third annual feast day is the Feast of Weeks, or Pentecost (Leviticus 23:16-21; Acts 2:1). This festival, which corresponded with the first harvest of the season, was the day God miraculously granted His Spirit to the New Testament Church (Acts 2).

Pentecost continues to remind us that God is the Lord of His harvest, choosing and preparing the firstfruits of His coming Kingdom by granting them His Spirit (Matthew 9:38; Luke 10:2; Romans 8:23; James 1:18). God's Spirit empowers us with the love of God, the motivation to obey Him, and a sound mind to discern His truth (2 Timothy 1:7; John 15:26; 16:13). Only those led by God's Spirit are called the Sons of God (Romans 8:9, 14).
