'Fearless' in the Bible

Great is my confidence in you; great is my pride and boasting on your behalf. I am filled [to the brim] with comfort; I am overflowing with joy in spite of all our trouble.

Now I, Paul, urge you by the gentleness and graciousness of Christ—I who am meek [so they say] when with you face to face, but bold [outspoken and fearless] toward you when absent!
