Today's Old Testament reading (Micah 7.7-15) unnecessarily splices right in the middle of a larger thought (vv. 1-15)--the idea that our trust must ultimately be placed only in the Lord, for people (both friends and enemies) will disappoint and betray us. Smack in the middle of this passage, Micah points us to God as our true hope.

But I will look to the LORD;
I will wait for the God of my salvation.
My God will hear me
-- Micah 7.7 CSB

But how do we look to and wait for God? As Christ reminds us in today's Gospel reading (Jn 15.1-11), such trust and reliance comes through abiding in him.

Remain in me, and I in you. Just as a branch is unable to produce fruit by itself unless it remains on the vine, neither can you unless you remain in me. I am the vine; you are the branches. The one who remains in me and I in him produces much fruit, because you can do nothing without me.
-- John 15.4-5 CSB

As we abide and remain in Christ, his presence dwells in us through the Spirit. And through the indwelling Spirit, we are led to rest in his grace, trust in his timing, and place our hope in him above all earthly things.

Moreover, our lives become marked by good works, which the Spirit gives us desire and ability to do the good works God has prescribed in Scripture. As St. Cyril of Alexandria writes:

Just as the root of the vine administers and distributes to the branches the benefit of its own natural and inherent qualities, so too the only-begotten Word of God imparts to the saints, as it were, a likeness to his own nature and the nature of God the Father by giving them the Spirit, insomuch as they have been united with him through faith and perfect holiness. Christ nourishes them in piety and works in them the knowledge of all virtue and good works (Cyril of Alexandria, Commentary on the Gospel of John).
