when do we pray?

​Continually Rejoice always, pray without ceasing, give thanks in all circumstances; for this is the will of God in Christ Jesus for you. -1 Thess 5:16-18

Constantly All these with one accord were devoting themselves to prayer. -Acts 1:14a Rejoice in hope, be patient in tribulation, be constant in prayer.  -Rom 12:12

Always Praying at all times in the Spirit, with all prayer and supplication. To that end keep alert with all perseverance, making supplication for all the saints. -Eph 6:18

In the day of trouble In the day of my trouble I call upon you, for you answer me.  -Ps 86:7

In Suffering Is anyone among you suffering? Let him pray.  Is anyone cheerful?  Let him sing praise.  -James 5:13
