May the Lord direct your hearts into the love of God, and into the patience of Christ.
Our love for God, (Rom 8 is about God’s love for us.) cf. Romans 5:8, 2 Peter 3:9. Paul’s prayer for them is that their love for God will lead them to continue, to persevere, in patiently waiting for Christ’ return. (Problems here are whether to take the "love" and the "patience" as objective or subjective. )
