How are Christians connected to the promises made to Israel?

Christians share in the blessings and promises of God originally given to Israel due to their faith in Christ, who is the fulfillment of those promises. Romans 11:17-20 illustrates this concept by explaining how wild olive branches (the Gentiles) are grafted into the good olive tree (Israel). This grafting indicates that believers are united in Christ and thus part of the spiritual household of God. By faith, Christians are not merely spectators but integral participants in the covenant promises, having been adopted into the family of God. This unity underscores that God's plan for redemption encompasses all who believe, regardless of their ethnic background, emphasizing the inclusivity of His grace.
