Psalm 63:3-4: “The Whole Church Says, “Amen!”
Psalm 63:3-4: Because your steadfast love is better than life,
my lips will praise you.
4 So I will bless you as long as I live;
in your name I will lift up my hands. 
What an incredible statement of faith from an exiled king!  These verses reflect the church’s heart, especially for martyrs.  Holding God’s love in Christ as more precious than anything is core to Christianity.  Also, verse 4 shows David’s private devotional life “was completed by what was outward and corporate, as verse 2 has shown, the one reinforcing the other.”  “Lift up my hands” refers common actions in congregation worship.  This language is in the New Testament, and shows the mutual relationship between personal and “corporate” worship. 
What is the application from these verses? First, God’s love is superior to everything. We know this because of the Trinity’s love toward us in Christ.  Consequently, every other love is secondary. If we love finances, personal security, other beliefs, other people, etc. more than the Triune God, we sin. Here is where all can fall. May we repent and turn to Christ. For the unbeliever: you must turn because eternal life is at stake.  For sinners and saints: suffering is worsened when we distrust Christ—may He spare us from false hopes.  Lastly, if we claim to follow Christ, our private devotion must be reflected in our corporate worship. If we lack in one, we might also lack in the other. Complete your worship by having both.
