'Assured' in the Bible

and being fully assured that what he had promised, he was able also to perform.

One man esteemeth one day above another: another esteemeth every day alike . Let each man be fully assured in his own mind.

Epaphras, who is one of you, a servant of Christ Jesus, saluteth you, always striving for you in his prayers, that ye may stand perfect and fully assured in all the will of God.

But abide thou in the things which thou hast learned and hast been assured of, knowing of whom thou hast learned them.
