'Edified' in the Bible

So the church throughout Judea and Galilee and Samaria enjoyed peace [without persecution], being built up [in wisdom, virtue, and faith]; and walking in the fear of the Lord and in the comfort and encouragement of the Holy Spirit, it continued to grow [in numbers].

Now I wish that all of you spoke in unknown tongues, but even more [I wish] that you would prophesy. The one who prophesies is greater [and more useful] than the one who speaks in tongues, unless he translates or explains [what he says], so that the church may be edified [instructed, improved, strengthened].

You are giving thanks well enough [in a way that God is glorified], but the other person [who does not understand you] is not edified [and spiritually strengthened since he cannot join in your thanksgiving].
