5We pray that our Lord Jesus would enable you to continue knowing that God loves you. We pray also that Christ will cause you to continue being steadfast (OR, being steadfast as he was steadfast).
5We want Jesus Christ, our leader, to help you understand more about God, and to understand that he really loves you. And we want him to help you to keep going strong, just like Jesus Christ kept going strong when he was here on the earth.
5And the Lord (ad)dress your hearts, in the charity of God, and in the patience of Christ. (And the Lord direct your hearts, in the love of God, and in the endurance of the Messiah.)
