Dr. Richard Barcellos elaborates for us in his recent book Better Than The Beginning: Creation in Biblical Perspective:
What the Old Testament typified in Israel (i.e., God’s son and firstborn), finds its fulfillment in Jesus, God’s faithful Son and firstborn, and His body, the church. Due to Christ’s faithfulness, He obtains an eternal inheritance for all those He came to save, unlike Adam and Israel who were unfaithful. The New Testament interprets Christ’s coming as the fulfillment of Israel’s hopes (e.g., Luke 1:26-38, 46-55, 67-79; 2:25-38; Acts 26:19-23). The New Testament also understands the church as the fulfillment of the eschatological Israel of Old Testament prophecy (e.g., Acts 2:14-21; 15:13-21; 2 Cor. 6:14-7:1; Gal. 6:16; Eph. 2:11-22; Heb. 8:7-13). The Lord’s servant, Jesus Christ, unlike Old Covenant Israel, was faithful and became a “light both to the Jewish people and to the Gentiles” (Acts 26:23), just as “the Prophets and Moses said was going to take place” (Acts 26:22).
Old Testament Israel was a means to an end. The end is not Palestine. The end is not an earthly, Jerusalem temple at which animal sacrifices are offered. Ancient Israel was chosen by God to be a means through which the last Adam would come. She was also a means through which His Person, His work, His people, and His kingdom were typified. Israel has connections with the first man, Adam, and the last Adam, Jesus Christ.
The Bible is God’s book. It possesses a unity, a progress of thought, and a goal that only God could ensure. It is not a book containing fallible records of two of the world’s most prominent religions. It is the infallible Word of God. It is God’s record of how He will get glory for Himself through what He does through His Son, the Lord Jesus Christ.
…Jesus Christ suffered for our sins then was rewarded for His obedience by being raised from the dead and exalted to the right hand of God in heaven. He will come again. He will transform the bodies of believers into bodies like His and will usher in a new heaven and new earth. In that place, He will be the center of attention. That eternal place is better than the garden of Eden and Israel’s land. Indeed, it may be called Emmanuel’s land. Emmanuel means “God with us.”*
