In Christ, you are in covenant with God, not with the world and its gods.
Salvation must be all of God for this reason: All are under the power of sin and entirely unable to contribute to their salvation.
In Christ, you are a holy nation, in the world but not of the world.
Your justification is grounded in God's mercy, not your own merit.
Christ was faithful to the end, and in him your zeal for the fight is refreshed.
As God brings final justice soon, disciples persevere by prayer and faith.
