'Convinced' in the Bible

Even though we speak like this, dear friends, we are convinced of better things in your case, things that point to salvation.

Now faith is being sure of what we hope for, being convinced of what we do not see.

By faith Sarah, even though she was old and barren, received the strength to conceive, because she was convinced that the one who had made the promise was faithful.

Pray for us; for we are convinced that we have a clear conscience, wanting to conduct ourselves honorably in everything.
