Psalm 124: This psalm is a simple statement about our ultimate security coming from the Lord. The psalmist does not mistakenly credit his own, or the nation’s abilities, but recognizes that it is only by the Lord’s grace that they have made it thus far. “If it had not bee the Lord who was on our side when people rose up against us, then they would have swallowed us up alive” (vs. 2-3).
Psalm 125: This psalm is in the series of psalms of ascent (120-134), which were short songs sung by faithful Jews during their seasonal pilgrimages to Jerusalem for the high festivals of the Jewish calendar. This song offers Mount Zion, to which the chanters are marching, as a simile for the faithful. They are strong and immovable, and the Lord protects them as the mountains protect Jerusalem (vs. 2).
Psalm 126: This psalm is a short reflection on the reality that the Lord has done good to his people in the past (vs. 1-3), and will do so again (vs. 4-6). Our hope that God will work for our good in the future is rooted in our remembrance of the good he has done in the past. Remembrance is a strong tool in the hands of God’s people.
Acts 3:12-26: In Mark’s sermon yesterday, he argued that the purpose of God’s prophets is to announce the message that God has put within their mouth. This is true of all the Old Testament prophets who received the word of the Lord throughout their ministries, and it is true of Jesus, who comes as the one ‘like Moses,’ whose coming is foretold in Deuteronomy 18:15. In this passage in Acts, Peter connects the canonical dots for us and reminds us that the prophet foretold in Deuteronomy is Jesus, and that as the true prophet, we should listen to him, because the word of God is in his mouth.
