Colossians 1:23

[And this He will do] provided that you continue to stay with and in the faith [in Christ], well-grounded and settled and steadfast, not shifting or moving away from the hope [which rests on and is inspired by] the glad tidings (the Gospel), which you heard and which has been preached [as being designed for and offered without restrictions] to every person under heaven, and of which [Gospel] I, Paul, became a minister.
