No prayer is no life! The Acts church did make it a priority. Mighty things happened because these people new it is the key to the Holy Spirit moving. The former and latter rain brings holiness into our lives. End of Acts, that know world was turn upside down for Jesus Christ.
Prayer, and not to becoming formalized prayer. Praying continually (I Thessalonians 5:17 -- yes, and wow!). an example toward clarification: brothers from different small gatherings hope to be coming together on the evening of this November 10th (downtown Portland, OR) for prayer, and to know more of what is in prayer for this city/region; then, they (we) will continue in prayer through days and hours to follow: reflecting how prayer is vital, with praying while meeting together being a smaller portion of the whole.
Possibly someone reading here may be able to confirm this from another place?
