'Proof' in the Bible

For to this end I also wrote, that I might know the proof of you, whether you are obedient in all things.

how that in much proof of affliction the abundance of their joy and their deep poverty abounded to the riches of their liberality.

Therefore show the proof of your love to them in front of the assemblies, and of our boasting on your behalf.

seeing that through the proof given by this service, they glorify God for the obedience of your confession to the Good News of Christ, and for the liberality of your contribution to them and to all;

seeing that you seek a proof of Christ who speaks in me; who toward you is not weak, but is powerful in you.

and in nothing frightened by the adversaries, which is for them a proof of destruction, but to you of salvation, and that from God.

But you know the proof of him, that, as a child serves a father, so he served with me in furtherance of the Good News.

Now faith is assurance of things hoped for, proof of things not seen.

that the proof of your faith, which is more precious than gold that perishes even though it is tested by fire, may be found to result in praise, glory, and honor at the revelation of Jesus Christ --
