Acts 5:20

All the words of this life - All the doctrines of life eternal, founded on the word, death, and resurrection of Christ Jesus. This is another periphrasis for Gospel. Go to the temple - the most public place, and speak to the people - who come there to worship according to the law, the words of this life - the whole doctrine of salvation from sin and death; and show that the law is fulfilled in the sacrifice of Jesus, and that, by his resurrection, he has brought life and immortality to light.

In the temple - In a public and conspicuous place. In this way there would be a most striking exhibition of their boldness; a proof that "God" had delivered them, and a manifestation of their purpose to obey God rather than man.

All the words - All the doctrines. Compare John 6:68, "Thou hast the words of eternal life."

Of this life - Pertaining to life, to the eternal life which they taught through the resurrection of Jesus. The word "life" is used sometimes to express "the whole of religion," as opposed to the spiritual "death" of sin. See John 1:4; John 3:36. Their deliverance from prison was not that they might be idle, and escape to a place of safety. Again they were to engage in the toils and perils which they had just before encountered. God delivers us from dangers sometimes that we may plunge "into" new dangers; he preserves us from one form of calamity that we may be tried in some new furnace of affliction; he calls us to encounter trials simply "because" he demands it, and as an expression of gratitude to him for his gracious interposition.

5:20 The words of this - That is, these words of life: words which show the way to life everlasting.
