The terms blessed and cursed are covenant words. God works through covenant to bless people. Believers in the Lord Jesus Christ are blessed through the everlasting covenant (Hebrews 13:20-21). By faith in Christ, we enter a covenant relationship with God. Those who reject salvation in Christ are cursed, cut off from a covenant relationship with God.
We are blessed by God, as Abraham was in Genesis. He was justified before God by faith. And he believed in the LORD, and He accounted it unto him for righteousness (Genesis 15:6). We are blessed by God today through faith in the Lord Jesus Christ. We are blessed to receive the righteousness of God in Christ (2 Corinthians 5:21).
God promised to bless Abraham and make him a blessing through the covenant promise in Genesis 12:1-3. God gave him this promise: In you all the nations shall be blessed. God promised to bless the nations through Abraham's Seed who is Christ (Galatians 3:16).
Old Testament believers were blessed by the promise of the Messiah who was coming. As believers today, we know that He has come that the blessing of Abraham might come upon the Gentiles in Christ Jesus, that we might receive the promise of the Spirit through faith (Galatians 3:14). We are blessed in Christ.
