Passage
Being therefore a prophet, and knowing that God had sworn to him with an oath, of the fruit of his loins to set upon his throne;
Being therefore a prophet, and knowing that God had sworn to him with an oath, of the fruit of his loins to set upon his throne;
Acts 2:28 Thou hast made known to me [the] paths of life, thou wilt fill me with joy with thy countenance.
Acts 2:29 Brethren, let it be allowed to speak with freedom to you concerning the patriarch David, that he has both died and been buried, and his monument is amongst us unto this day.
Acts 2:30 Being therefore a prophet, and knowing that God had sworn to him with an oath, of the fruit of his loins to set upon his throne;
Acts 2:31 he, seeing [it] before, spoke concerning the resurrection of the Christ, that neither has he been left in hades nor his flesh seen corruption.
Acts 2:32 This Jesus has God raised up, whereof all *we* are witnesses.
The verse centers on "therefore", "prophet", "knowing", "sworn", "oath", "fruit", "loins", and "upon". It is saying that the verse draws attention to "therefore" and "prophet", so its meaning should be read from those terms before moving to application.
The nearby context moves from verse 29's "Brethren let it be allowed to speak..." into verse 31's "he seeing it before spoke concerning the...", so "therefore" and "prophet" belong inside that flow. In Acts context, the local focus is Christ, faith, and discipleship.
A plain takeaway is to answer the verse's own emphasis on "therefore" and "prophet" with trust shaped by these words, not by a vague optimism outside the passage.
