Meekness
is,
Softness of temper; mildness; gentleness;
bearing injuries patiently.
Also,
Humility; submission to God's
will without murmuring.
Being meek is the
opposite of being
proud or
arrogant. 

But the fruit of the Spirit is love, joy,
peace, longsuffering, gentleness,
goodness, faith, meekness, temperance:
against such there is no law.
And they that are Christ's have crucified
the flesh with the affections and lusts. 
If we live in the Spirit,
let us also walk in the Spirit.

Galatians 5:22-26
