According to Christianity, spiritual blessings are good things God wishes upon people, and they are better and higher than material blessings. Ephesians 1:3 says that God's people are blessed with all spiritual blessings in Christ Jesus. Spiritual blessings are the primary benefits of having a relationship with God through Christ.
Spiritual blessings mentioned in Ephesians 1:3 include the election of God's people into sainthood -- that His people are holy and blameless -- and adoption of God's people as His children. The power to become God's sons is given to those who believe in the Gospel and redemption through His blood, and through Christ's death God's people are saved from eternal condemnation.
Other spiritual blessings outlined in Ephesians are the forgiveness of sins, receiving wisdom and insight through His word, redemption through Christ's blood and receiving the Holy Spirit.
