'Fully' in the Bible

and being fully convinced that what he had promised, he was also able to do.

One person prefers [one] day over [another] day, and another person regards every day [alike]. Each one must be fully convinced in his own mind.

by the power of signs and wonders, by the power of the Spirit, so that from Jerusalem and [traveling] around as far as Illyricum I have fully proclaimed the gospel of Christ.
