'Assurance' in the Bible

because He did set a day in which He is about to judge the world in righteousness, by a man whom He did ordain, having given assurance to all, having raised him out of the dead.'

that their hearts may be comforted, being united in love, and to all riches of the full assurance of the understanding, to the full knowledge of the secret of the God and Father, and of the Christ,

because our good news did not come to you in word only, but also in power, and in the Holy Spirit, and in much assurance, even as ye have known of what sort we became among you because of you,

And thou -- watch in all things; suffer evil; do the work of one proclaiming good news; of thy ministration make full assurance,

and we desire each one of you the same diligence to shew, unto the full assurance of the hope unto the end,

may we draw near with a true heart, in full assurance of faith, having the hearts sprinkled from an evil conscience, and having the body bathed with pure water;
