You can mix humility and pride as long as the latter is of the justifiable kind that doesn't stem from the feeling of self-importance.
St. John the Baptist didn't feel fit to stoop and untie the sandal straps of Jesus. We are not worthy to receive the Lord in the Holy Eucharist. But since he did institute this sacrament specifically for our reception to remember him, we are to override our feeling of unworthiness to receive him. God's wishes should always come first. In fact, only his wishes, not ours, should prevail.
Jesus wants us to be shining lights in the world. Therefore, we must proudly "show off" our light by example for all to see, never to be ashamed of the Lord and what he has done for us. This is holy pride.
