and were continually in the temple blessing God.
It is the description of what the disciples were doing when they discovered that the mysterious individual who had been appearing among them was, as some suspected, the Lord Jesus risen from the dead.
Remember at the beginning of Luke that the reason he writes is for Theophilus,
that you may have certainty concerning the things you have been taught.
By the time that Luke finishes his gospel, he thinks he has achieved his goal. The result? Those who have certainty are in the temple 'blessing God'.
The Christian life is characterized by thankfulness, focussed on and inspired by the mighty work of God.
