Acts 1:14 These all continued with one accord in prayer and supplication, with the women and Mary the mother of Jesus, and with His brothers.
After Jesus had ascended into Heaven, the disciples withdrew for a time of prayer. They did not go off alone and sulk but came together with the women to pray.
It was not as if one of them suggested prayer and the others came along not to be ashamed; they all came together with one mind and that was to pray.
Have you got the idea that pray is important yet? This is what Jesus taught and how the disciples listened. We ought to as well!
