'Boldness' in the Bible

Now, little children, remain in him, that when he appears, we may have boldness, and not be ashamed before him at his coming.

Beloved, if our hearts don't condemn us, we have boldness toward God;

In this love has been made perfect among us, that we may have boldness in the day of judgment, because as he is, even so are we in this world.

This is the boldness which we have toward him, that, if we ask anything according to his will, he listens to us.
