'Confidence' in the Bible

Now, little children, abide in Him, so that when He appears, we may have confidence and not shrink away from Him in shame at His coming.

Beloved, if our heart does not condemn us, we have confidence before God;

By this, love is perfected with us, so that we may have confidence in the day of judgment; because as He is, so also are we in this world.

This is the confidence which we have before Him, that, if we ask anything according to His will, He hears us.
