Titus 2:6-8
6 Likewise urge the young men to be sensible; 7 in all things show yourself to be an example of good deeds, with purity in doctrine, dignified, 8 sound in speech which is beyond reproach, so that the opponent will be put to shame, having nothing bad to say about us.
put to shame
By our good actions and our good words and deeds the enemies of the faith will be put to shame. In our sound teaching and our constant application of that doctrine, the people who write books and make their living opposing the Christian faith will be ashamed by our words and deeds. Imagine how powerful the witness of love is in the sight of even the most gross and disgusting accusation. This is the power of every believer who rests in Christ. As we walk in the Spirit the fruit of the Spirit will grow.
