In Ephesians 3-4, Paul continues his explanation of and praise for God’s plan of salvation, “the Gentiles are fellow heirs, members of the same body, and partakers of the promise in Christ Jesus through the gospel”. This was a “mystery hidden for ages”, so that now “we have boldness and access with confidence through our faith in” Christ.
Paul praises God for planning and revealing this inclusion of the Gentiles, “now to him who is able to do far more abundantly than all we ask or think, according to the power at work within us, to him be glory in the church and in Christ Jesus throughout all generations, forever and ever.”
Paul also urges us “to walk in a manner worthy of the calling to which you have been called, with all humility and gentleness, with patience, bearing with one another in love, eager to maintain the unity of the Spirit in the bond of peace“. That is the hard part of being a disciple, overcoming our pride, putting others higher than ourselves in order to work together as a unified body, building “itself up in love”.
