building yourselves: To forever reform themselves according to the Holy Spirit’s guidance; in other words, by building congregations up, by their preaching, in the teaching of the Holy Spirit. (Oecumenius)
praying in the Holy Spirit: To pray in the Spirit always means to offer prayer to God with a clean conscience and a pure faith. If we live a good life the Holy Spirit dwells with us and we can receive what we ask for. (Ambrosiaster Eph 6:18)
