Acts 2:47; Acts 5:14; Acts 6:7; Acts 11:21). For the phrase, Ἐστερεοῦντο τῇ πίστει, "They were made firm in the faith," comp. Colossians 2:5, Τὸ στερέωμα τῆς εἰς Ξριστὸν πίστεως ὑμῶν, "The steadfastness of your faith." The word is used in its physical sense in Acts 3:7, Ἐστερεώθησαν αὐτοῦ αἱ βάσεις κ.τ.λ., "His feet and anklebones received strength," became fast and firm instead of being loose and vacillating.

Of Christ, both in the grace and doctrine of faith; and that both by the preaching of the Gospel by the apostle and his companions, and by the decrees of the elders delivered by him:

and increased in number daily; as well as in gifts and grace.
