What does the Bible teach about the connection between feasts and grace?

The feasts outlined in Exodus signify a divine invitation for Israel to recognize God's grace in their lives. Through the Feast of Weeks and the Feast of Ingathering, the people celebrated God's provision, both spiritually and materially. These occasions serve as a reminder that all good gifts come from God, reinforcing the connection between His grace and our reliance upon Him. This aligns with Reformed thought on grace being unmerited favor, where believers gather in thanksgiving and worship, acknowledging what God has accomplished for them through Christ.
