The following is a chronological sequence of the biblical references to God’s New Covenant.
- Around 1405 B.C., Moses alluded to God’s New Covenant (Deut. 30:1-6).
- Around 835 B.C., Joel mentioned God’s promise of pouring out the Holy
Spirit on all mankind—an aspect of God’s New Covenant (Joel 2:28-32).
- Around 588 B.C., Jeremiah specifically mentioned God’s New Covenant (Jer. 31:31-34).
- Around 585 B.C., Ezekiel referred to God’s “everlasting covenant” (aka God’s New Covenant) in specific details (Ezek. 36:24-27 for details; 37:26-28 for everlasting).
The Ezek. 36 details: 25I will sprinkle clean water on you, and you will be
clean (cf. John 13:5-10); I will cleanse you from all your filthiness and
from all your idols. 26Moreover, I will give you a new heart (spiritual,
not physical) and put a new spirit within you; and I will remove the heart
of stone from your flesh and give you a heart of flesh. 27I will put My
Spirit within you and cause you (not enable or empower you) to walk
in My statutes, and you will be careful to observe My ordinances.
- Sometime around A.D. 27, Jesus alluded to God’s New Covenant while speaking to Nicodemus (a Pharisee, ruler, and teacher) by mentioning one being “born again” (John 3:3-8; cf. Ezek. 36:26-27).

- On or about A.D. 30, God’s New Covenant became operational at Pentecost (Acts 2:1-40).
- Peter then explained the phenomena at Pentecost of the Spirit’s presence, an integral part of God’s New Covenant (Acts 2:14-38).
- On A.D. 34, Jesus made an announcement to Saul on his way to Damascus—an announcement that gentiles would receive forgiveness of sins and sanctification in Jesus’ name—a clear reference to God’s New Covenant (Acts 26:18).
- During A.D. 54, Paul outlined a celebration of the Lord’s Supper (Communion) for observance at a local church (1 Cor. 11:23-28).
