Psalm 34:13-15

Keep your tongue from evil and your lips from speaking deceit. Turn away from evil and do good; seek peace and pursue it. The eyes of the Lord are toward the righteous (those with moral courage and spiritual integrity). And His ears are open to their cry. 

We control our peace in this life by our attitude, actions, and what we speak. Doing good is more than just an action. It is what God calls us to do. As we stay in line with the word, we remain righteous, and the Lord hears our cry when we call because we keep ourselves from sin and speaking deceit.
