It is only through Jesus and by faith, that we can receive the blessings in Ephesians 1:1-7. There is only one who intercedes between God and man and it is Christ Jesus [1 Timothy 2:5]. It is only in Jesus and believing in the Gospel that we can receive spiritual blessings in the heavenly places.

The saints on this earth are those who believe in the Gospel. The life in Jesus Christ does not simply refer to an ethically virtuous life, but refers to a life that praises the blessing of salvation received freely in Him.

Although the saints' lives may seem fruitless based on the standards of this world, spiritually speaking, these are the lives that seek after the highest desires and the greatest faith. The saints are living their lives blessed with the spiritual blessings that belong to Heaven, in the Gospel of Christ and by their faith. 

They are the ones who through the Gospel come to know and believe Jesus as their Savior and who have received the spiritual blessings in the heavenly places.
