From my Life Application Bible, about Psalm 110...
This is one of the most-quoted psalms in the New Testament because of its clear references to the Messiah. In Matthew 22:41-45, Jesus quote Psalm 110:1 and applied it to himself. There are several other references to the Messiah in this psalm: Christ's final and total destruction of the wicked(Ps 110:1, 6; see Rev 6-9); Christ's reign on the earth (Ps 110:2; see Rev 20:1-7); Christ's priestly work for his people (Ps 110:3-4; see Heb 5-8); and the final battle on earth when Christ will overcome the forces of evil (Ps 110:5-6; see Rev 19:11-21).
Many people have a vague belief in God but refuse to accept Jesus as anything more than a great human teacher. But the Bible does not allow that option. Both the Old and New Testaments proclaim the deity of the one who cam to save and to reign.
Psalm 122: I was glad when they said to me, "Let us go to the house of the Lord".
Do we delight in going to church, like David did, or do we consider it a chore we have to do. Often our attitude towards church is a reflection of our attitude towards Jesus. If we don't enjoy church, maybe we need to examine our relationship with God.
Psalm 131 reminds us of the dangers of pride. It is almost impossible to proud and content or trusting in God's faithfulness. Pride takes our focus off of God, and puts it on ourselves instead. The consequences of which are predictably bad.
Psalm 133 reminds us of the importance of living in harmony with those around us. This doesn't mean we need to always agree on everything, but we need to learn how to agree to disagree on matters that are really not doctrinally important, and to love each other particularly when we disagree with each other.
